Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472064, here are decompositions:
- 11 + 31472053 = 31472064
- 23 + 31472041 = 31472064
- 53 + 31472011 = 31472064
- 61 + 31472003 = 31472064
- 73 + 31471991 = 31472064
- 97 + 31471967 = 31472064
- 131 + 31471933 = 31472064
- 157 + 31471907 = 31472064
Showing the first eight; more decompositions exist.
