Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971620, here are decompositions:
- 13 + 4294971607 = 4294971620
- 151 + 4294971469 = 4294971620
- 229 + 4294971391 = 4294971620
- 241 + 4294971379 = 4294971620
- 271 + 4294971349 = 4294971620
- 421 + 4294971199 = 4294971620
- 523 + 4294971097 = 4294971620
- 547 + 4294971073 = 4294971620
Showing the first eight; more decompositions exist.
