Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387522, here are decompositions:
- 19 + 2147387503 = 2147387522
- 109 + 2147387413 = 2147387522
- 139 + 2147387383 = 2147387522
- 199 + 2147387323 = 2147387522
- 223 + 2147387299 = 2147387522
- 439 + 2147387083 = 2147387522
- 463 + 2147387059 = 2147387522
- 601 + 2147386921 = 2147387522
Showing the first eight; more decompositions exist.
