Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535232, here are decompositions:

5 + 31535227 = 31535232
13 + 31535219 = 31535232
19 + 31535213 = 31535232
59 + 31535173 = 31535232
61 + 31535171 = 31535232
89 + 31535143 = 31535232
101 + 31535131 = 31535232
109 + 31535123 = 31535232

Showing the first eight; more decompositions exist.
