Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18554, here are decompositions:
- 13 + 18541 = 18554
- 31 + 18523 = 18554
- 37 + 18517 = 18554
- 61 + 18493 = 18554
- 73 + 18481 = 18554
- 97 + 18457 = 18554
- 103 + 18451 = 18554
- 127 + 18427 = 18554
Showing the first eight; more decompositions exist.
