Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486324, here are decompositions:

17 + 31486307 = 31486324
41 + 31486283 = 31486324
53 + 31486271 = 31486324
71 + 31486253 = 31486324
383 + 31485941 = 31486324
431 + 31485893 = 31486324
491 + 31485833 = 31486324
521 + 31485803 = 31486324

Showing the first eight; more decompositions exist.
