Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535396, here are decompositions:

19 + 31535377 = 31535396
163 + 31535233 = 31535396
223 + 31535173 = 31535396
283 + 31535113 = 31535396
313 + 31535083 = 31535396
337 + 31535059 = 31535396
397 + 31534999 = 31535396
523 + 31534873 = 31535396

Showing the first eight; more decompositions exist.
