Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387444, here are decompositions:
- 3 + 2147387441 = 2147387444
- 31 + 2147387413 = 2147387444
- 61 + 2147387383 = 2147387444
- 313 + 2147387131 = 2147387444
- 457 + 2147386987 = 2147387444
- 523 + 2147386921 = 2147387444
- 691 + 2147386753 = 2147387444
- 733 + 2147386711 = 2147387444
Showing the first eight; more decompositions exist.
