Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147477082, here are decompositions:
- 19 + 2147477063 = 2147477082
- 53 + 2147477029 = 2147477082
- 61 + 2147477021 = 2147477082
- 103 + 2147476979 = 2147477082
- 131 + 2147476951 = 2147477082
- 139 + 2147476943 = 2147477082
- 151 + 2147476931 = 2147477082
- 211 + 2147476871 = 2147477082
Showing the first eight; more decompositions exist.
