Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535206, here are decompositions:

23 + 31535183 = 31535206
83 + 31535123 = 31535206
149 + 31535057 = 31535206
173 + 31535033 = 31535206
293 + 31534913 = 31535206
419 + 31534787 = 31535206
449 + 31534757 = 31535206
467 + 31534739 = 31535206

Showing the first eight; more decompositions exist.
