Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387048, here are decompositions:
- 19 + 2147387029 = 2147387048
- 31 + 2147387017 = 2147387048
- 61 + 2147386987 = 2147387048
- 127 + 2147386921 = 2147387048
- 337 + 2147386711 = 2147387048
- 349 + 2147386699 = 2147387048
- 409 + 2147386639 = 2147387048
- 421 + 2147386627 = 2147387048
Showing the first eight; more decompositions exist.
