Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523182, here are decompositions:

71 + 31523111 = 31523182
83 + 31523099 = 31523182
101 + 31523081 = 31523182
179 + 31523003 = 31523182
281 + 31522901 = 31523182
293 + 31522889 = 31523182
359 + 31522823 = 31523182
569 + 31522613 = 31523182

Showing the first eight; more decompositions exist.
