Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387718, here are decompositions:
- 5 + 2147387713 = 2147387718
- 19 + 2147387699 = 2147387718
- 41 + 2147387677 = 2147387718
- 67 + 2147387651 = 2147387718
- 71 + 2147387647 = 2147387718
- 89 + 2147387629 = 2147387718
- 109 + 2147387609 = 2147387718
- 211 + 2147387507 = 2147387718
Showing the first eight; more decompositions exist.
