Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972742, here are decompositions:
- 79 + 4294972663 = 4294972742
- 139 + 4294972603 = 4294972742
- 163 + 4294972579 = 4294972742
- 331 + 4294972411 = 4294972742
- 349 + 4294972393 = 4294972742
- 409 + 4294972333 = 4294972742
- 499 + 4294972243 = 4294972742
- 673 + 4294972069 = 4294972742
Showing the first eight; more decompositions exist.
