Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12618, here are decompositions:
- 5 + 12613 = 12618
- 7 + 12611 = 12618
- 17 + 12601 = 12618
- 29 + 12589 = 12618
- 41 + 12577 = 12618
- 71 + 12547 = 12618
- 79 + 12539 = 12618
- 101 + 12517 = 12618
Showing the first eight; more decompositions exist.
