Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957778, here are decompositions:
- 61 + 4294957717 = 4294957778
- 79 + 4294957699 = 4294957778
- 379 + 4294957399 = 4294957778
- 409 + 4294957369 = 4294957778
- 571 + 4294957207 = 4294957778
- 829 + 4294956949 = 4294957778
- 877 + 4294956901 = 4294957778
- 1129 + 4294956649 = 4294957778
Showing the first eight; more decompositions exist.
