Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9218, here are decompositions:
- 19 + 9199 = 9218
- 31 + 9187 = 9218
- 37 + 9181 = 9218
- 61 + 9157 = 9218
- 67 + 9151 = 9218
- 109 + 9109 = 9218
- 127 + 9091 = 9218
- 151 + 9067 = 9218
Showing the first eight; more decompositions exist.
