Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975490, here are decompositions:
- 19 + 4294975471 = 4294975490
- 37 + 4294975453 = 4294975490
- 73 + 4294975417 = 4294975490
- 79 + 4294975411 = 4294975490
- 97 + 4294975393 = 4294975490
- 151 + 4294975339 = 4294975490
- 193 + 4294975297 = 4294975490
- 367 + 4294975123 = 4294975490
Showing the first eight; more decompositions exist.
