Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535226, here are decompositions:

7 + 31535219 = 31535226
13 + 31535213 = 31535226
43 + 31535183 = 31535226
53 + 31535173 = 31535226
83 + 31535143 = 31535226
103 + 31535123 = 31535226
113 + 31535113 = 31535226
167 + 31535059 = 31535226

Showing the first eight; more decompositions exist.
