Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535150, here are decompositions:

7 + 31535143 = 31535150
19 + 31535131 = 31535150
37 + 31535113 = 31535150
43 + 31535107 = 31535150
67 + 31535083 = 31535150
139 + 31535011 = 31535150
151 + 31534999 = 31535150
271 + 31534879 = 31535150

Showing the first eight; more decompositions exist.
