Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425882, here are decompositions:
- 3 + 2147425879 = 2147425882
- 11 + 2147425871 = 2147425882
- 29 + 2147425853 = 2147425882
- 599 + 2147425283 = 2147425882
- 743 + 2147425139 = 2147425882
- 761 + 2147425121 = 2147425882
- 809 + 2147425073 = 2147425882
- 881 + 2147425001 = 2147425882
Showing the first eight; more decompositions exist.
