Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975640, here are decompositions:
- 13 + 4294975627 = 4294975640
- 79 + 4294975561 = 4294975640
- 97 + 4294975543 = 4294975640
- 103 + 4294975537 = 4294975640
- 223 + 4294975417 = 4294975640
- 229 + 4294975411 = 4294975640
- 271 + 4294975369 = 4294975640
- 523 + 4294975117 = 4294975640
Showing the first eight; more decompositions exist.
