Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425698, here are decompositions:
- 17 + 2147425681 = 2147425698
- 107 + 2147425591 = 2147425698
- 139 + 2147425559 = 2147425698
- 157 + 2147425541 = 2147425698
- 167 + 2147425531 = 2147425698
- 179 + 2147425519 = 2147425698
- 191 + 2147425507 = 2147425698
- 241 + 2147425457 = 2147425698
Showing the first eight; more decompositions exist.
