Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90172, here are decompositions:

23 + 90149 = 90172
83 + 90089 = 90172
101 + 90071 = 90172
113 + 90059 = 90172
149 + 90023 = 90172
233 + 89939 = 90172
263 + 89909 = 90172
281 + 89891 = 90172

Showing the first eight; more decompositions exist.
