Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535014, here are decompositions:

3 + 31535011 = 31535014
53 + 31534961 = 31535014
101 + 31534913 = 31535014
227 + 31534787 = 31535014
257 + 31534757 = 31535014
263 + 31534751 = 31535014
383 + 31534631 = 31535014
461 + 31534553 = 31535014

Showing the first eight; more decompositions exist.
