Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535142, here are decompositions:

11 + 31535131 = 31535142
19 + 31535123 = 31535142
29 + 31535113 = 31535142
59 + 31535083 = 31535142
61 + 31535081 = 31535142
83 + 31535059 = 31535142
109 + 31535033 = 31535142
131 + 31535011 = 31535142

Showing the first eight; more decompositions exist.
