Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87582, here are decompositions:
- 23 + 87559 = 87582
- 29 + 87553 = 87582
- 41 + 87541 = 87582
- 43 + 87539 = 87582
- 59 + 87523 = 87582
- 71 + 87511 = 87582
- 73 + 87509 = 87582
- 101 + 87481 = 87582
Showing the first eight; more decompositions exist.
