Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89640, here are decompositions:
- 7 + 89633 = 89640
- 13 + 89627 = 89640
- 29 + 89611 = 89640
- 37 + 89603 = 89640
- 41 + 89599 = 89640
- 43 + 89597 = 89640
- 73 + 89567 = 89640
- 79 + 89561 = 89640
Showing the first eight; more decompositions exist.
