Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502998, here are decompositions:

5 + 31502993 = 31502998
71 + 31502927 = 31502998
101 + 31502897 = 31502998
311 + 31502687 = 31502998
509 + 31502489 = 31502998
557 + 31502441 = 31502998
719 + 31502279 = 31502998
809 + 31502189 = 31502998

Showing the first eight; more decompositions exist.
