Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22178, here are decompositions:
- 7 + 22171 = 22178
- 19 + 22159 = 22178
- 31 + 22147 = 22178
- 67 + 22111 = 22178
- 127 + 22051 = 22178
- 139 + 22039 = 22178
- 151 + 22027 = 22178
- 181 + 21997 = 22178
Showing the first eight; more decompositions exist.
