Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535296, here are decompositions:

83 + 31535213 = 31535296
113 + 31535183 = 31535296
173 + 31535123 = 31535296
239 + 31535057 = 31535296
263 + 31535033 = 31535296
383 + 31534913 = 31535296
509 + 31534787 = 31535296
557 + 31534739 = 31535296

Showing the first eight; more decompositions exist.
