Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524508, here are decompositions:

89 + 31524419 = 31524508
251 + 31524257 = 31524508
311 + 31524197 = 31524508
347 + 31524161 = 31524508
401 + 31524107 = 31524508
461 + 31524047 = 31524508
569 + 31523939 = 31524508
839 + 31523669 = 31524508

Showing the first eight; more decompositions exist.
