Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87530, here are decompositions:
- 7 + 87523 = 87530
- 13 + 87517 = 87530
- 19 + 87511 = 87530
- 97 + 87433 = 87530
- 103 + 87427 = 87530
- 109 + 87421 = 87530
- 127 + 87403 = 87530
- 193 + 87337 = 87530
Showing the first eight; more decompositions exist.
