Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474522, here are decompositions:
- 3 + 31474519 = 31474522
- 41 + 31474481 = 31474522
- 89 + 31474433 = 31474522
- 179 + 31474343 = 31474522
- 269 + 31474253 = 31474522
- 449 + 31474073 = 31474522
- 461 + 31474061 = 31474522
- 479 + 31474043 = 31474522
Showing the first eight; more decompositions exist.
