Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972378, here are decompositions:
- 41 + 4294972337 = 4294972378
- 71 + 4294972307 = 4294972378
- 227 + 4294972151 = 4294972378
- 269 + 4294972109 = 4294972378
- 317 + 4294972061 = 4294972378
- 449 + 4294971929 = 4294972378
- 821 + 4294971557 = 4294972378
- 881 + 4294971497 = 4294972378
Showing the first eight; more decompositions exist.
