Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425390, here are decompositions:
- 41 + 2147425349 = 2147425390
- 107 + 2147425283 = 2147425390
- 251 + 2147425139 = 2147425390
- 263 + 2147425127 = 2147425390
- 269 + 2147425121 = 2147425390
- 317 + 2147425073 = 2147425390
- 389 + 2147425001 = 2147425390
- 491 + 2147424899 = 2147425390
Showing the first eight; more decompositions exist.
