Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490052, here are decompositions:

29 + 31490023 = 31490052
53 + 31489999 = 31490052
89 + 31489963 = 31490052
103 + 31489949 = 31490052
109 + 31489943 = 31490052
151 + 31489901 = 31490052
173 + 31489879 = 31490052
179 + 31489873 = 31490052

Showing the first eight; more decompositions exist.
