Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535546, here are decompositions:

43 + 31535503 = 31535546
79 + 31535467 = 31535546
127 + 31535419 = 31535546
283 + 31535263 = 31535546
313 + 31535233 = 31535546
373 + 31535173 = 31535546
433 + 31535113 = 31535546
439 + 31535107 = 31535546

Showing the first eight; more decompositions exist.
