Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522386, here are decompositions:
- 13 + 31522373 = 31522386
- 23 + 31522363 = 31522386
- 29 + 31522357 = 31522386
- 47 + 31522339 = 31522386
- 59 + 31522327 = 31522386
- 73 + 31522313 = 31522386
- 89 + 31522297 = 31522386
- 109 + 31522277 = 31522386
Showing the first eight; more decompositions exist.
