Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387804, here are decompositions:
- 13 + 2147387791 = 2147387804
- 61 + 2147387743 = 2147387804
- 127 + 2147387677 = 2147387804
- 157 + 2147387647 = 2147387804
- 421 + 2147387383 = 2147387804
- 547 + 2147387257 = 2147387804
- 577 + 2147387227 = 2147387804
- 673 + 2147387131 = 2147387804
Showing the first eight; more decompositions exist.
