Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572946, here are decompositions:
- 3 + 31572943 = 31572946
- 5 + 31572941 = 31572946
- 137 + 31572809 = 31572946
- 233 + 31572713 = 31572946
- 557 + 31572389 = 31572946
- 599 + 31572347 = 31572946
- 683 + 31572263 = 31572946
- 719 + 31572227 = 31572946
Showing the first eight; more decompositions exist.
