Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523014, here are decompositions:

11 + 31523003 = 31523014
53 + 31522961 = 31523014
113 + 31522901 = 31523014
167 + 31522847 = 31523014
191 + 31522823 = 31523014
401 + 31522613 = 31523014
431 + 31522583 = 31523014
461 + 31522553 = 31523014

Showing the first eight; more decompositions exist.
