Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572982, here are decompositions:
- 3 + 31572979 = 31572982
- 11 + 31572971 = 31572982
- 41 + 31572941 = 31572982
- 101 + 31572881 = 31572982
- 113 + 31572869 = 31572982
- 173 + 31572809 = 31572982
- 251 + 31572731 = 31572982
- 269 + 31572713 = 31572982
Showing the first eight; more decompositions exist.
