Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506634, here are decompositions:

113 + 31506521 = 31506634
191 + 31506443 = 31506634
197 + 31506437 = 31506634
281 + 31506353 = 31506634
461 + 31506173 = 31506634
563 + 31506071 = 31506634
641 + 31505993 = 31506634
821 + 31505813 = 31506634

Showing the first eight; more decompositions exist.
