Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524272, here are decompositions:

79 + 31524193 = 31524272
139 + 31524133 = 31524272
181 + 31524091 = 31524272
223 + 31524049 = 31524272
229 + 31524043 = 31524272
331 + 31523941 = 31524272
421 + 31523851 = 31524272
433 + 31523839 = 31524272

Showing the first eight; more decompositions exist.
