Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972690, here are decompositions:
- 131 + 4294972559 = 4294972690
- 257 + 4294972433 = 4294972690
- 269 + 4294972421 = 4294972690
- 353 + 4294972337 = 4294972690
- 383 + 4294972307 = 4294972690
- 641 + 4294972049 = 4294972690
- 653 + 4294972037 = 4294972690
- 761 + 4294971929 = 4294972690
Showing the first eight; more decompositions exist.
