Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147477272, here are decompositions:
- 23 + 2147477249 = 2147477272
- 71 + 2147477201 = 2147477272
- 113 + 2147477159 = 2147477272
- 179 + 2147477093 = 2147477272
- 251 + 2147477021 = 2147477272
- 293 + 2147476979 = 2147477272
- 401 + 2147476871 = 2147477272
- 431 + 2147476841 = 2147477272
Showing the first eight; more decompositions exist.
