Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87524, here are decompositions:
- 7 + 87517 = 87524
- 13 + 87511 = 87524
- 43 + 87481 = 87524
- 97 + 87427 = 87524
- 103 + 87421 = 87524
- 211 + 87313 = 87524
- 271 + 87253 = 87524
- 313 + 87211 = 87524
Showing the first eight; more decompositions exist.
