Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524236, here are decompositions:

13 + 31524223 = 31524236
43 + 31524193 = 31524236
103 + 31524133 = 31524236
193 + 31524043 = 31524236
223 + 31524013 = 31524236
283 + 31523953 = 31524236
397 + 31523839 = 31524236
433 + 31523803 = 31524236

Showing the first eight; more decompositions exist.
