Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90220, here are decompositions:

3 + 90217 = 90220
17 + 90203 = 90220
23 + 90197 = 90220
29 + 90191 = 90220
47 + 90173 = 90220
71 + 90149 = 90220
113 + 90107 = 90220
131 + 90089 = 90220

Showing the first eight; more decompositions exist.
