Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425742, here are decompositions:
- 13 + 2147425729 = 2147425742
- 31 + 2147425711 = 2147425742
- 61 + 2147425681 = 2147425742
- 79 + 2147425663 = 2147425742
- 151 + 2147425591 = 2147425742
- 211 + 2147425531 = 2147425742
- 223 + 2147425519 = 2147425742
- 229 + 2147425513 = 2147425742
Showing the first eight; more decompositions exist.
