Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523002, here are decompositions:

23 + 31522979 = 31523002
41 + 31522961 = 31523002
101 + 31522901 = 31523002
113 + 31522889 = 31523002
179 + 31522823 = 31523002
389 + 31522613 = 31523002
419 + 31522583 = 31523002
449 + 31522553 = 31523002

Showing the first eight; more decompositions exist.
