Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147455502, here are decompositions:
- 13 + 2147455489 = 2147455502
- 43 + 2147455459 = 2147455502
- 139 + 2147455363 = 2147455502
- 211 + 2147455291 = 2147455502
- 271 + 2147455231 = 2147455502
- 421 + 2147455081 = 2147455502
- 499 + 2147455003 = 2147455502
- 739 + 2147454763 = 2147455502
Showing the first eight; more decompositions exist.
