Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975142, here are decompositions:
- 19 + 4294975123 = 4294975142
- 151 + 4294974991 = 4294975142
- 223 + 4294974919 = 4294975142
- 229 + 4294974913 = 4294975142
- 331 + 4294974811 = 4294975142
- 349 + 4294974793 = 4294975142
- 373 + 4294974769 = 4294975142
- 691 + 4294974451 = 4294975142
Showing the first eight; more decompositions exist.
