Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606370, here are decompositions:

31 + 31606339 = 31606370
73 + 31606297 = 31606370
109 + 31606261 = 31606370
283 + 31606087 = 31606370
457 + 31605913 = 31606370
547 + 31605823 = 31606370
613 + 31605757 = 31606370
643 + 31605727 = 31606370

Showing the first eight; more decompositions exist.
