Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978856, here are decompositions:
- 79 + 4294978777 = 4294978856
- 127 + 4294978729 = 4294978856
- 229 + 4294978627 = 4294978856
- 367 + 4294978489 = 4294978856
- 457 + 4294978399 = 4294978856
- 523 + 4294978333 = 4294978856
- 547 + 4294978309 = 4294978856
- 607 + 4294978249 = 4294978856
Showing the first eight; more decompositions exist.
