Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610030, here are decompositions:

7 + 31610023 = 31610030
19 + 31610011 = 31610030
37 + 31609993 = 31610030
73 + 31609957 = 31610030
97 + 31609933 = 31610030
181 + 31609849 = 31610030
211 + 31609819 = 31610030
271 + 31609759 = 31610030

Showing the first eight; more decompositions exist.
