Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425942, here are decompositions:
- 5 + 2147425937 = 2147425942
- 71 + 2147425871 = 2147425942
- 89 + 2147425853 = 2147425942
- 383 + 2147425559 = 2147425942
- 401 + 2147425541 = 2147425942
- 593 + 2147425349 = 2147425942
- 659 + 2147425283 = 2147425942
- 773 + 2147425169 = 2147425942
Showing the first eight; more decompositions exist.
