Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387760, here are decompositions:
- 17 + 2147387743 = 2147387760
- 19 + 2147387741 = 2147387760
- 31 + 2147387729 = 2147387760
- 41 + 2147387719 = 2147387760
- 47 + 2147387713 = 2147387760
- 61 + 2147387699 = 2147387760
- 83 + 2147387677 = 2147387760
- 109 + 2147387651 = 2147387760
Showing the first eight; more decompositions exist.
