Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387750, here are decompositions:
- 7 + 2147387743 = 2147387750
- 31 + 2147387719 = 2147387750
- 37 + 2147387713 = 2147387750
- 73 + 2147387677 = 2147387750
- 103 + 2147387647 = 2147387750
- 337 + 2147387413 = 2147387750
- 367 + 2147387383 = 2147387750
- 523 + 2147387227 = 2147387750
Showing the first eight; more decompositions exist.
