Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425804, here are decompositions:
- 197 + 2147425607 = 2147425804
- 263 + 2147425541 = 2147425804
- 347 + 2147425457 = 2147425804
- 521 + 2147425283 = 2147425804
- 617 + 2147425187 = 2147425804
- 677 + 2147425127 = 2147425804
- 683 + 2147425121 = 2147425804
- 701 + 2147425103 = 2147425804
Showing the first eight; more decompositions exist.
