Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89730, here are decompositions:
- 41 + 89689 = 89730
- 59 + 89671 = 89730
- 61 + 89669 = 89730
- 71 + 89659 = 89730
- 73 + 89657 = 89730
- 97 + 89633 = 89730
- 103 + 89627 = 89730
- 127 + 89603 = 89730
Showing the first eight; more decompositions exist.
