Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68642, here are decompositions:
- 3 + 68639 = 68642
- 31 + 68611 = 68642
- 61 + 68581 = 68642
- 103 + 68539 = 68642
- 151 + 68491 = 68642
- 193 + 68449 = 68642
- 199 + 68443 = 68642
- 271 + 68371 = 68642
Showing the first eight; more decompositions exist.
