Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523104, here are decompositions:

5 + 31523099 = 31523104
23 + 31523081 = 31523104
83 + 31523021 = 31523104
101 + 31523003 = 31523104
167 + 31522937 = 31523104
257 + 31522847 = 31523104
281 + 31522823 = 31523104
491 + 31522613 = 31523104

Showing the first eight; more decompositions exist.
