Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489508, here are decompositions:
- 19 + 31489489 = 31489508
- 97 + 31489411 = 31489508
- 109 + 31489399 = 31489508
- 229 + 31489279 = 31489508
- 331 + 31489177 = 31489508
- 439 + 31489069 = 31489508
- 499 + 31489009 = 31489508
- 577 + 31488931 = 31489508
Showing the first eight; more decompositions exist.
