Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615226, here are decompositions:
- 73 + 31615153 = 31615226
- 163 + 31615063 = 31615226
- 283 + 31614943 = 31615226
- 337 + 31614889 = 31615226
- 367 + 31614859 = 31615226
- 373 + 31614853 = 31615226
- 397 + 31614829 = 31615226
- 439 + 31614787 = 31615226
Showing the first eight; more decompositions exist.
