Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501592, here are decompositions:

61 + 31501531 = 31501592
193 + 31501399 = 31501592
271 + 31501321 = 31501592
373 + 31501219 = 31501592
613 + 31500979 = 31501592
673 + 31500919 = 31501592
739 + 31500853 = 31501592
1033 + 31500559 = 31501592

Showing the first eight; more decompositions exist.
