Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535134, here are decompositions:

3 + 31535131 = 31535134
11 + 31535123 = 31535134
53 + 31535081 = 31535134
101 + 31535033 = 31535134
173 + 31534961 = 31535134
263 + 31534871 = 31535134
347 + 31534787 = 31535134
383 + 31534751 = 31535134

Showing the first eight; more decompositions exist.
