Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535246, here are decompositions:

13 + 31535233 = 31535246
19 + 31535227 = 31535246
73 + 31535173 = 31535246
103 + 31535143 = 31535246
139 + 31535107 = 31535246
163 + 31535083 = 31535246
367 + 31534879 = 31535246
373 + 31534873 = 31535246

Showing the first eight; more decompositions exist.
