Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7228, here are decompositions:
- 17 + 7211 = 7228
- 41 + 7187 = 7228
- 101 + 7127 = 7228
- 107 + 7121 = 7228
- 149 + 7079 = 7228
- 227 + 7001 = 7228
- 251 + 6977 = 7228
- 257 + 6971 = 7228
Showing the first eight; more decompositions exist.
