Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387058, here are decompositions:
- 29 + 2147387029 = 2147387058
- 41 + 2147387017 = 2147387058
- 71 + 2147386987 = 2147387058
- 137 + 2147386921 = 2147387058
- 331 + 2147386727 = 2147387058
- 347 + 2147386711 = 2147387058
- 359 + 2147386699 = 2147387058
- 419 + 2147386639 = 2147387058
Showing the first eight; more decompositions exist.
