Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387682, here are decompositions:
- 5 + 2147387677 = 2147387682
- 31 + 2147387651 = 2147387682
- 53 + 2147387629 = 2147387682
- 73 + 2147387609 = 2147387682
- 109 + 2147387573 = 2147387682
- 151 + 2147387531 = 2147387682
- 179 + 2147387503 = 2147387682
- 241 + 2147387441 = 2147387682
Showing the first eight; more decompositions exist.
