Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971980, here are decompositions:
- 37 + 4294971943 = 4294971980
- 43 + 4294971937 = 4294971980
- 97 + 4294971883 = 4294971980
- 139 + 4294971841 = 4294971980
- 151 + 4294971829 = 4294971980
- 199 + 4294971781 = 4294971980
- 307 + 4294971673 = 4294971980
- 337 + 4294971643 = 4294971980
Showing the first eight; more decompositions exist.
