Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971870, here are decompositions:
- 11 + 4294971859 = 4294971870
- 29 + 4294971841 = 4294971870
- 41 + 4294971829 = 4294971870
- 89 + 4294971781 = 4294971870
- 197 + 4294971673 = 4294971870
- 227 + 4294971643 = 4294971870
- 263 + 4294971607 = 4294971870
- 307 + 4294971563 = 4294971870
Showing the first eight; more decompositions exist.
