Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535062, here are decompositions:

3 + 31535059 = 31535062
5 + 31535057 = 31535062
29 + 31535033 = 31535062
101 + 31534961 = 31535062
149 + 31534913 = 31535062
191 + 31534871 = 31535062
263 + 31534799 = 31535062
311 + 31534751 = 31535062

Showing the first eight; more decompositions exist.
