Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12548, here are decompositions:
- 7 + 12541 = 12548
- 31 + 12517 = 12548
- 37 + 12511 = 12548
- 61 + 12487 = 12548
- 97 + 12451 = 12548
- 127 + 12421 = 12548
- 139 + 12409 = 12548
- 157 + 12391 = 12548
Showing the first eight; more decompositions exist.
