Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975478, here are decompositions:
- 7 + 4294975471 = 4294975478
- 61 + 4294975417 = 4294975478
- 67 + 4294975411 = 4294975478
- 109 + 4294975369 = 4294975478
- 139 + 4294975339 = 4294975478
- 181 + 4294975297 = 4294975478
- 331 + 4294975147 = 4294975478
- 421 + 4294975057 = 4294975478
Showing the first eight; more decompositions exist.
