Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536486, here are decompositions:

5 + 31536481 = 31536486
83 + 31536403 = 31536486
89 + 31536397 = 31536486
103 + 31536383 = 31536486
127 + 31536359 = 31536486
139 + 31536347 = 31536486
173 + 31536313 = 31536486
193 + 31536293 = 31536486

Showing the first eight; more decompositions exist.
