Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489324, here are decompositions:

107 + 31489217 = 31489324
131 + 31489193 = 31489324
227 + 31489097 = 31489324
233 + 31489091 = 31489324
281 + 31489043 = 31489324
353 + 31488971 = 31489324
557 + 31488767 = 31489324
677 + 31488647 = 31489324

Showing the first eight; more decompositions exist.
