Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972644, here are decompositions:
- 31 + 4294972613 = 4294972644
- 41 + 4294972603 = 4294972644
- 163 + 4294972481 = 4294972644
- 211 + 4294972433 = 4294972644
- 223 + 4294972421 = 4294972644
- 233 + 4294972411 = 4294972644
- 251 + 4294972393 = 4294972644
- 293 + 4294972351 = 4294972644
Showing the first eight; more decompositions exist.
