Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425888, here are decompositions:
- 17 + 2147425871 = 2147425888
- 281 + 2147425607 = 2147425888
- 347 + 2147425541 = 2147425888
- 431 + 2147425457 = 2147425888
- 701 + 2147425187 = 2147425888
- 719 + 2147425169 = 2147425888
- 761 + 2147425127 = 2147425888
- 821 + 2147425067 = 2147425888
Showing the first eight; more decompositions exist.
