Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425860, here are decompositions:
- 7 + 2147425853 = 2147425860
- 101 + 2147425759 = 2147425860
- 131 + 2147425729 = 2147425860
- 149 + 2147425711 = 2147425860
- 179 + 2147425681 = 2147425860
- 197 + 2147425663 = 2147425860
- 269 + 2147425591 = 2147425860
- 347 + 2147425513 = 2147425860
Showing the first eight; more decompositions exist.
