Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610018, here are decompositions:

7 + 31610011 = 31610018
61 + 31609957 = 31610018
157 + 31609861 = 31610018
199 + 31609819 = 31610018
241 + 31609777 = 31610018
277 + 31609741 = 31610018
409 + 31609609 = 31610018
457 + 31609561 = 31610018

Showing the first eight; more decompositions exist.
