Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972390, here are decompositions:
- 53 + 4294972337 = 4294972390
- 83 + 4294972307 = 4294972390
- 239 + 4294972151 = 4294972390
- 281 + 4294972109 = 4294972390
- 311 + 4294972079 = 4294972390
- 353 + 4294972037 = 4294972390
- 461 + 4294971929 = 4294972390
- 827 + 4294971563 = 4294972390
Showing the first eight; more decompositions exist.
