Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294977072, here are decompositions:
- 5 + 4294977067 = 4294977072
- 131 + 4294976941 = 4294977072
- 233 + 4294976839 = 4294977072
- 349 + 4294976723 = 4294977072
- 433 + 4294976639 = 4294977072
- 523 + 4294976549 = 4294977072
- 571 + 4294976501 = 4294977072
- 619 + 4294976453 = 4294977072
Showing the first eight; more decompositions exist.
