Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22158, here are decompositions:
- 5 + 22153 = 22158
- 11 + 22147 = 22158
- 29 + 22129 = 22158
- 47 + 22111 = 22158
- 67 + 22091 = 22158
- 79 + 22079 = 22158
- 107 + 22051 = 22158
- 127 + 22031 = 22158
Showing the first eight; more decompositions exist.
