Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524302, here are decompositions:

31 + 31524271 = 31524302
79 + 31524223 = 31524302
109 + 31524193 = 31524302
211 + 31524091 = 31524302
349 + 31523953 = 31524302
421 + 31523881 = 31524302
463 + 31523839 = 31524302
499 + 31523803 = 31524302

Showing the first eight; more decompositions exist.
