Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73686, here are decompositions:
- 5 + 73681 = 73686
- 7 + 73679 = 73686
- 13 + 73673 = 73686
- 43 + 73643 = 73686
- 73 + 73613 = 73686
- 79 + 73607 = 73686
- 89 + 73597 = 73686
- 97 + 73589 = 73686
Showing the first eight; more decompositions exist.
