Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294976978, here are decompositions:
- 37 + 4294976941 = 4294976978
- 139 + 4294976839 = 4294976978
- 181 + 4294976797 = 4294976978
- 547 + 4294976431 = 4294976978
- 619 + 4294976359 = 4294976978
- 631 + 4294976347 = 4294976978
- 709 + 4294976269 = 4294976978
- 757 + 4294976221 = 4294976978
Showing the first eight; more decompositions exist.
