Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535274, here are decompositions:

11 + 31535263 = 31535274
41 + 31535233 = 31535274
47 + 31535227 = 31535274
61 + 31535213 = 31535274
101 + 31535173 = 31535274
103 + 31535171 = 31535274
131 + 31535143 = 31535274
151 + 31535123 = 31535274

Showing the first eight; more decompositions exist.
