Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971842, here are decompositions:
- 13 + 4294971829 = 4294971842
- 61 + 4294971781 = 4294971842
- 199 + 4294971643 = 4294971842
- 373 + 4294971469 = 4294971842
- 463 + 4294971379 = 4294971842
- 541 + 4294971301 = 4294971842
- 643 + 4294971199 = 4294971842
- 673 + 4294971169 = 4294971842
Showing the first eight; more decompositions exist.
