Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975646, here are decompositions:
- 19 + 4294975627 = 4294975646
- 103 + 4294975543 = 4294975646
- 109 + 4294975537 = 4294975646
- 193 + 4294975453 = 4294975646
- 229 + 4294975417 = 4294975646
- 277 + 4294975369 = 4294975646
- 307 + 4294975339 = 4294975646
- 349 + 4294975297 = 4294975646
Showing the first eight; more decompositions exist.
