Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90130, here are decompositions:

3 + 90127 = 90130
23 + 90107 = 90130
41 + 90089 = 90130
59 + 90071 = 90130
71 + 90059 = 90130
107 + 90023 = 90130
113 + 90017 = 90130
167 + 89963 = 90130

Showing the first eight; more decompositions exist.
