Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622976, here are decompositions:
- 17 + 31622959 = 31622976
- 29 + 31622947 = 31622976
- 37 + 31622939 = 31622976
- 43 + 31622933 = 31622976
- 53 + 31622923 = 31622976
- 83 + 31622893 = 31622976
- 113 + 31622863 = 31622976
- 139 + 31622837 = 31622976
Showing the first eight; more decompositions exist.
