Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425180, here are decompositions:
- 11 + 2147425169 = 2147425180
- 41 + 2147425139 = 2147425180
- 53 + 2147425127 = 2147425180
- 59 + 2147425121 = 2147425180
- 107 + 2147425073 = 2147425180
- 113 + 2147425067 = 2147425180
- 179 + 2147425001 = 2147425180
- 281 + 2147424899 = 2147425180
Showing the first eight; more decompositions exist.
