Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90138, here are decompositions:

11 + 90127 = 90138
17 + 90121 = 90138
31 + 90107 = 90138
67 + 90071 = 90138
71 + 90067 = 90138
79 + 90059 = 90138
107 + 90031 = 90138
127 + 90011 = 90138

Showing the first eight; more decompositions exist.
