Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606174, here are decompositions:

107 + 31606067 = 31606174
113 + 31606061 = 31606174
191 + 31605983 = 31606174
401 + 31605773 = 31606174
461 + 31605713 = 31606174
617 + 31605557 = 31606174
683 + 31605491 = 31606174
773 + 31605401 = 31606174

Showing the first eight; more decompositions exist.
