Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294976578, here are decompositions:
- 29 + 4294976549 = 4294976578
- 41 + 4294976537 = 4294976578
- 59 + 4294976519 = 4294976578
- 131 + 4294976447 = 4294976578
- 197 + 4294976381 = 4294976578
- 257 + 4294976321 = 4294976578
- 317 + 4294976261 = 4294976578
- 359 + 4294976219 = 4294976578
Showing the first eight; more decompositions exist.
