Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425770, here are decompositions:
- 11 + 2147425759 = 2147425770
- 41 + 2147425729 = 2147425770
- 59 + 2147425711 = 2147425770
- 89 + 2147425681 = 2147425770
- 107 + 2147425663 = 2147425770
- 163 + 2147425607 = 2147425770
- 179 + 2147425591 = 2147425770
- 211 + 2147425559 = 2147425770
Showing the first eight; more decompositions exist.
