Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524382, here are decompositions:

89 + 31524293 = 31524382
359 + 31524023 = 31524382
443 + 31523939 = 31524382
941 + 31523441 = 31524382
971 + 31523411 = 31524382
983 + 31523399 = 31524382
1103 + 31523279 = 31524382
1151 + 31523231 = 31524382

Showing the first eight; more decompositions exist.
