Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1848, here are decompositions:
- 17 + 1831 = 1848
- 37 + 1811 = 1848
- 47 + 1801 = 1848
- 59 + 1789 = 1848
- 61 + 1787 = 1848
- 71 + 1777 = 1848
- 89 + 1759 = 1848
- 101 + 1747 = 1848
Showing the first eight; more decompositions exist.

The digit sequence 1848 first appears in π at position 21,754 of the decimal expansion (the 21,754ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
