Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425388, here are decompositions:
- 7 + 2147425381 = 2147425388
- 79 + 2147425309 = 2147425388
- 139 + 2147425249 = 2147425388
- 151 + 2147425237 = 2147425388
- 439 + 2147424949 = 2147425388
- 571 + 2147424817 = 2147425388
- 601 + 2147424787 = 2147425388
- 811 + 2147424577 = 2147425388
Showing the first eight; more decompositions exist.
