Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425990, here are decompositions:
- 11 + 2147425979 = 2147425990
- 53 + 2147425937 = 2147425990
- 137 + 2147425853 = 2147425990
- 383 + 2147425607 = 2147425990
- 431 + 2147425559 = 2147425990
- 449 + 2147425541 = 2147425990
- 641 + 2147425349 = 2147425990
- 821 + 2147425169 = 2147425990
Showing the first eight; more decompositions exist.
