Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147463778, here are decompositions:
- 11 + 2147463767 = 2147463778
- 17 + 2147463761 = 2147463778
- 41 + 2147463737 = 2147463778
- 137 + 2147463641 = 2147463778
- 179 + 2147463599 = 2147463778
- 431 + 2147463347 = 2147463778
- 479 + 2147463299 = 2147463778
- 521 + 2147463257 = 2147463778
Showing the first eight; more decompositions exist.
