Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294973638, here are decompositions:
- 5 + 4294973633 = 4294973638
- 89 + 4294973549 = 4294973638
- 101 + 4294973537 = 4294973638
- 107 + 4294973531 = 4294973638
- 251 + 4294973387 = 4294973638
- 317 + 4294973321 = 4294973638
- 491 + 4294973147 = 4294973638
- 521 + 4294973117 = 4294973638
Showing the first eight; more decompositions exist.
