Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535236, here are decompositions:

3 + 31535233 = 31535236
17 + 31535219 = 31535236
23 + 31535213 = 31535236
53 + 31535183 = 31535236
113 + 31535123 = 31535236
179 + 31535057 = 31535236
449 + 31534787 = 31535236
479 + 31534757 = 31535236

Showing the first eight; more decompositions exist.
