Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497182, here are decompositions:

43 + 31497139 = 31497182
181 + 31497001 = 31497182
193 + 31496989 = 31497182
373 + 31496809 = 31497182
463 + 31496719 = 31497182
571 + 31496611 = 31497182
631 + 31496551 = 31497182
643 + 31496539 = 31497182

Showing the first eight; more decompositions exist.
