Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294973778, here are decompositions:
- 19 + 4294973759 = 4294973778
- 61 + 4294973717 = 4294973778
- 107 + 4294973671 = 4294973778
- 127 + 4294973651 = 4294973778
- 149 + 4294973629 = 4294973778
- 167 + 4294973611 = 4294973778
- 191 + 4294973587 = 4294973778
- 229 + 4294973549 = 4294973778
Showing the first eight; more decompositions exist.
