Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523082, here are decompositions:

29 + 31523053 = 31523082
61 + 31523021 = 31523082
79 + 31523003 = 31523082
103 + 31522979 = 31523082
131 + 31522951 = 31523082
181 + 31522901 = 31523082
193 + 31522889 = 31523082
389 + 31522693 = 31523082

Showing the first eight; more decompositions exist.
