Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387744, here are decompositions:
- 3 + 2147387741 = 2147387744
- 31 + 2147387713 = 2147387744
- 67 + 2147387677 = 2147387744
- 97 + 2147387647 = 2147387744
- 241 + 2147387503 = 2147387744
- 331 + 2147387413 = 2147387744
- 421 + 2147387323 = 2147387744
- 487 + 2147387257 = 2147387744
Showing the first eight; more decompositions exist.
