Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425258, here are decompositions:
- 71 + 2147425187 = 2147425258
- 89 + 2147425169 = 2147425258
- 131 + 2147425127 = 2147425258
- 137 + 2147425121 = 2147425258
- 191 + 2147425067 = 2147425258
- 257 + 2147425001 = 2147425258
- 359 + 2147424899 = 2147425258
- 389 + 2147424869 = 2147425258
Showing the first eight; more decompositions exist.
