Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147477088, here are decompositions:
- 59 + 2147477029 = 2147477088
- 67 + 2147477021 = 2147477088
- 109 + 2147476979 = 2147477088
- 137 + 2147476951 = 2147477088
- 151 + 2147476937 = 2147477088
- 157 + 2147476931 = 2147477088
- 191 + 2147476897 = 2147477088
- 269 + 2147476819 = 2147477088
Showing the first eight; more decompositions exist.
