Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45720, here are decompositions:
- 13 + 45707 = 45720
- 23 + 45697 = 45720
- 29 + 45691 = 45720
- 43 + 45677 = 45720
- 47 + 45673 = 45720
- 53 + 45667 = 45720
- 61 + 45659 = 45720
- 79 + 45641 = 45720
Showing the first eight; more decompositions exist.
