Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387308, here are decompositions:
- 29 + 2147387279 = 2147387308
- 89 + 2147387219 = 2147387308
- 641 + 2147386667 = 2147387308
- 701 + 2147386607 = 2147387308
- 1031 + 2147386277 = 2147387308
- 1049 + 2147386259 = 2147387308
- 1091 + 2147386217 = 2147387308
- 1097 + 2147386211 = 2147387308
Showing the first eight; more decompositions exist.
