Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524206, here are decompositions:

13 + 31524193 = 31524206
73 + 31524133 = 31524206
157 + 31524049 = 31524206
163 + 31524043 = 31524206
193 + 31524013 = 31524206
367 + 31523839 = 31524206
457 + 31523749 = 31524206
499 + 31523707 = 31524206

Showing the first eight; more decompositions exist.
