Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489424, here are decompositions:
- 7 + 31489417 = 31489424
- 13 + 31489411 = 31489424
- 61 + 31489363 = 31489424
- 181 + 31489243 = 31489424
- 277 + 31489147 = 31489424
- 397 + 31489027 = 31489424
- 433 + 31488991 = 31489424
- 691 + 31488733 = 31489424
Showing the first eight; more decompositions exist.
