Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523074, here are decompositions:

47 + 31523027 = 31523074
53 + 31523021 = 31523074
71 + 31523003 = 31523074
113 + 31522961 = 31523074
137 + 31522937 = 31523074
173 + 31522901 = 31523074
227 + 31522847 = 31523074
251 + 31522823 = 31523074

Showing the first eight; more decompositions exist.
