Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425708, here are decompositions:
- 101 + 2147425607 = 2147425708
- 149 + 2147425559 = 2147425708
- 167 + 2147425541 = 2147425708
- 251 + 2147425457 = 2147425708
- 359 + 2147425349 = 2147425708
- 521 + 2147425187 = 2147425708
- 569 + 2147425139 = 2147425708
- 587 + 2147425121 = 2147425708
Showing the first eight; more decompositions exist.
