Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73680, here are decompositions:
- 7 + 73673 = 73680
- 29 + 73651 = 73680
- 37 + 73643 = 73680
- 43 + 73637 = 73680
- 67 + 73613 = 73680
- 71 + 73609 = 73680
- 73 + 73607 = 73680
- 83 + 73597 = 73680
Showing the first eight; more decompositions exist.
