Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610148, here are decompositions:

5 + 31610143 = 31610148
7 + 31610141 = 31610148
41 + 31610107 = 31610148
67 + 31610081 = 31610148
109 + 31610039 = 31610148
137 + 31610011 = 31610148
139 + 31610009 = 31610148
181 + 31609967 = 31610148

Showing the first eight; more decompositions exist.
