Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18174, here are decompositions:
- 5 + 18169 = 18174
- 31 + 18143 = 18174
- 41 + 18133 = 18174
- 43 + 18131 = 18174
- 47 + 18127 = 18174
- 53 + 18121 = 18174
- 97 + 18077 = 18174
- 113 + 18061 = 18174
Showing the first eight; more decompositions exist.
