Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42582, here are decompositions:
- 5 + 42577 = 42582
- 11 + 42571 = 42582
- 13 + 42569 = 42582
- 73 + 42509 = 42582
- 83 + 42499 = 42582
- 109 + 42473 = 42582
- 131 + 42451 = 42582
- 139 + 42443 = 42582
Showing the first eight; more decompositions exist.
