Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972490, here are decompositions:
- 79 + 4294972411 = 4294972490
- 97 + 4294972393 = 4294972490
- 139 + 4294972351 = 4294972490
- 157 + 4294972333 = 4294972490
- 199 + 4294972291 = 4294972490
- 223 + 4294972267 = 4294972490
- 283 + 4294972207 = 4294972490
- 373 + 4294972117 = 4294972490
Showing the first eight; more decompositions exist.
