Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493662, here are decompositions:

89 + 31493573 = 31493662
149 + 31493513 = 31493662
461 + 31493201 = 31493662
491 + 31493171 = 31493662
509 + 31493153 = 31493662
593 + 31493069 = 31493662
653 + 31493009 = 31493662
719 + 31492943 = 31493662

Showing the first eight; more decompositions exist.
