Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528236, here are decompositions:

7 + 31528229 = 31528236
23 + 31528213 = 31528236
29 + 31528207 = 31528236
67 + 31528169 = 31528236
79 + 31528157 = 31528236
109 + 31528127 = 31528236
167 + 31528069 = 31528236
199 + 31528037 = 31528236

Showing the first eight; more decompositions exist.
