Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294974642, here are decompositions:
- 43 + 4294974599 = 4294974642
- 59 + 4294974583 = 4294974642
- 61 + 4294974581 = 4294974642
- 73 + 4294974569 = 4294974642
- 149 + 4294974493 = 4294974642
- 163 + 4294974479 = 4294974642
- 191 + 4294974451 = 4294974642
- 229 + 4294974413 = 4294974642
Showing the first eight; more decompositions exist.
