Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18524, here are decompositions:
- 3 + 18521 = 18524
- 7 + 18517 = 18524
- 31 + 18493 = 18524
- 43 + 18481 = 18524
- 67 + 18457 = 18524
- 73 + 18451 = 18524
- 97 + 18427 = 18524
- 127 + 18397 = 18524
Showing the first eight; more decompositions exist.
