Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971984, here are decompositions:
- 41 + 4294971943 = 4294971984
- 47 + 4294971937 = 4294971984
- 53 + 4294971931 = 4294971984
- 101 + 4294971883 = 4294971984
- 311 + 4294971673 = 4294971984
- 421 + 4294971563 = 4294971984
- 487 + 4294971497 = 4294971984
- 593 + 4294971391 = 4294971984
Showing the first eight; more decompositions exist.
