Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971890, here are decompositions:
- 7 + 4294971883 = 4294971890
- 31 + 4294971859 = 4294971890
- 61 + 4294971829 = 4294971890
- 109 + 4294971781 = 4294971890
- 283 + 4294971607 = 4294971890
- 421 + 4294971469 = 4294971890
- 499 + 4294971391 = 4294971890
- 523 + 4294971367 = 4294971890
Showing the first eight; more decompositions exist.
