Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610038, here are decompositions:

29 + 31610009 = 31610038
71 + 31609967 = 31610038
101 + 31609937 = 31610038
107 + 31609931 = 31610038
167 + 31609871 = 31610038
191 + 31609847 = 31610038
269 + 31609769 = 31610038
347 + 31609691 = 31610038

Showing the first eight; more decompositions exist.
