Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523106, here are decompositions:

7 + 31523099 = 31523106
53 + 31523053 = 31523106
79 + 31523027 = 31523106
103 + 31523003 = 31523106
127 + 31522979 = 31523106
233 + 31522873 = 31523106
283 + 31522823 = 31523106
359 + 31522747 = 31523106

Showing the first eight; more decompositions exist.
