Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18692, here are decompositions:
- 13 + 18679 = 18692
- 31 + 18661 = 18692
- 109 + 18583 = 18692
- 139 + 18553 = 18692
- 151 + 18541 = 18692
- 199 + 18493 = 18692
- 211 + 18481 = 18692
- 241 + 18451 = 18692
Showing the first eight; more decompositions exist.
