Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1830, here are decompositions:
- 7 + 1823 = 1830
- 19 + 1811 = 1830
- 29 + 1801 = 1830
- 41 + 1789 = 1830
- 43 + 1787 = 1830
- 47 + 1783 = 1830
- 53 + 1777 = 1830
- 71 + 1759 = 1830
Showing the first eight; more decompositions exist.

The digit sequence 1830 first appears in π at position 490 of the decimal expansion (the 490ordinal-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.
