Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1824, here are decompositions:
- 13 + 1811 = 1824
- 23 + 1801 = 1824
- 37 + 1787 = 1824
- 41 + 1783 = 1824
- 47 + 1777 = 1824
- 71 + 1753 = 1824
- 83 + 1741 = 1824
- 101 + 1723 = 1824
Showing the first eight; more decompositions exist.

The digit sequence 1824 first appears in π at position 30,154 of the decimal expansion (the 30,154ordinal-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.
