Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89680, here are decompositions:
- 11 + 89669 = 89680
- 23 + 89657 = 89680
- 47 + 89633 = 89680
- 53 + 89627 = 89680
- 83 + 89597 = 89680
- 89 + 89591 = 89680
- 113 + 89567 = 89680
- 167 + 89513 = 89680
Showing the first eight; more decompositions exist.
