Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523032, here are decompositions:

5 + 31523027 = 31523032
11 + 31523021 = 31523032
29 + 31523003 = 31523032
53 + 31522979 = 31523032
71 + 31522961 = 31523032
131 + 31522901 = 31523032
419 + 31522613 = 31523032
449 + 31522583 = 31523032

Showing the first eight; more decompositions exist.
