Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971920, here are decompositions:
- 37 + 4294971883 = 4294971920
- 61 + 4294971859 = 4294971920
- 79 + 4294971841 = 4294971920
- 139 + 4294971781 = 4294971920
- 277 + 4294971643 = 4294971920
- 313 + 4294971607 = 4294971920
- 541 + 4294971379 = 4294971920
- 571 + 4294971349 = 4294971920
Showing the first eight; more decompositions exist.
