Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12718, here are decompositions:
- 5 + 12713 = 12718
- 29 + 12689 = 12718
- 47 + 12671 = 12718
- 59 + 12659 = 12718
- 71 + 12647 = 12718
- 107 + 12611 = 12718
- 149 + 12569 = 12718
- 179 + 12539 = 12718
Showing the first eight; more decompositions exist.
