Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524466, here are decompositions:

47 + 31524419 = 31524466
173 + 31524293 = 31524466
269 + 31524197 = 31524466
359 + 31524107 = 31524466
419 + 31524047 = 31524466
443 + 31524023 = 31524466
797 + 31523669 = 31524466
887 + 31523579 = 31524466

Showing the first eight; more decompositions exist.
