Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523004, here are decompositions:

17 + 31522987 = 31523004
43 + 31522961 = 31523004
53 + 31522951 = 31523004
67 + 31522937 = 31523004
103 + 31522901 = 31523004
131 + 31522873 = 31523004
157 + 31522847 = 31523004
181 + 31522823 = 31523004

Showing the first eight; more decompositions exist.
