Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523974, here are decompositions:

173 + 31523801 = 31523974
563 + 31523411 = 31523974
593 + 31523381 = 31523974
743 + 31523231 = 31523974
773 + 31523201 = 31523974
863 + 31523111 = 31523974
947 + 31523027 = 31523974
953 + 31523021 = 31523974

Showing the first eight; more decompositions exist.
