Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517432, here are decompositions:

19 + 31517413 = 31517432
43 + 31517389 = 31517432
283 + 31517149 = 31517432
421 + 31517011 = 31517432
439 + 31516993 = 31517432
613 + 31516819 = 31517432
643 + 31516789 = 31517432
733 + 31516699 = 31517432

Showing the first eight; more decompositions exist.
