Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972892, here are decompositions:
- 31 + 4294972861 = 4294972892
- 103 + 4294972789 = 4294972892
- 229 + 4294972663 = 4294972892
- 283 + 4294972609 = 4294972892
- 313 + 4294972579 = 4294972892
- 499 + 4294972393 = 4294972892
- 541 + 4294972351 = 4294972892
- 601 + 4294972291 = 4294972892
Showing the first eight; more decompositions exist.
