Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503224, here are decompositions:

7 + 31503217 = 31503224
43 + 31503181 = 31503224
73 + 31503151 = 31503224
163 + 31503061 = 31503224
271 + 31502953 = 31503224
283 + 31502941 = 31503224
367 + 31502857 = 31503224
463 + 31502761 = 31503224

Showing the first eight; more decompositions exist.
