Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 36720, here are decompositions:
- 7 + 36713 = 36720
- 11 + 36709 = 36720
- 23 + 36697 = 36720
- 29 + 36691 = 36720
- 37 + 36683 = 36720
- 43 + 36677 = 36720
- 67 + 36653 = 36720
- 83 + 36637 = 36720
Showing the first eight; more decompositions exist.
