Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573982, here are decompositions:

151 + 31573831 = 31573982
163 + 31573819 = 31573982
229 + 31573753 = 31573982
421 + 31573561 = 31573982
619 + 31573363 = 31573982
829 + 31573153 = 31573982
859 + 31573123 = 31573982
1033 + 31572949 = 31573982

Showing the first eight; more decompositions exist.
