Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535002, here are decompositions:

3 + 31534999 = 31535002
41 + 31534961 = 31535002
89 + 31534913 = 31535002
131 + 31534871 = 31535002
251 + 31534751 = 31535002
263 + 31534739 = 31535002
293 + 31534709 = 31535002
311 + 31534691 = 31535002

Showing the first eight; more decompositions exist.
