Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18624, here are decompositions:
- 7 + 18617 = 18624
- 31 + 18593 = 18624
- 37 + 18587 = 18624
- 41 + 18583 = 18624
- 71 + 18553 = 18624
- 83 + 18541 = 18624
- 101 + 18523 = 18624
- 103 + 18521 = 18624
Showing the first eight; more decompositions exist.
