Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387936, here are decompositions:
- 3 + 2147387933 = 2147387936
- 79 + 2147387857 = 2147387936
- 97 + 2147387839 = 2147387936
- 193 + 2147387743 = 2147387936
- 223 + 2147387713 = 2147387936
- 307 + 2147387629 = 2147387936
- 433 + 2147387503 = 2147387936
- 523 + 2147387413 = 2147387936
Showing the first eight; more decompositions exist.
