Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18626, here are decompositions:
- 43 + 18583 = 18626
- 73 + 18553 = 18626
- 103 + 18523 = 18626
- 109 + 18517 = 18626
- 193 + 18433 = 18626
- 199 + 18427 = 18626
- 229 + 18397 = 18626
- 313 + 18313 = 18626
Showing the first eight; more decompositions exist.
