Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294977142, here are decompositions:
- 59 + 4294977083 = 4294977142
- 419 + 4294976723 = 4294977142
- 503 + 4294976639 = 4294977142
- 563 + 4294976579 = 4294977142
- 593 + 4294976549 = 4294977142
- 641 + 4294976501 = 4294977142
- 761 + 4294976381 = 4294977142
- 821 + 4294976321 = 4294977142
Showing the first eight; more decompositions exist.
