Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523362, here are decompositions:

53 + 31523309 = 31523362
83 + 31523279 = 31523362
131 + 31523231 = 31523362
251 + 31523111 = 31523362
263 + 31523099 = 31523362
281 + 31523081 = 31523362
359 + 31523003 = 31523362
383 + 31522979 = 31523362

Showing the first eight; more decompositions exist.
