Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610150, here are decompositions:

7 + 31610143 = 31610150
37 + 31610113 = 31610150
43 + 31610107 = 31610150
67 + 31610083 = 31610150
127 + 31610023 = 31610150
139 + 31610011 = 31610150
157 + 31609993 = 31610150
193 + 31609957 = 31610150

Showing the first eight; more decompositions exist.
