Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535182, here are decompositions:

11 + 31535171 = 31535182
59 + 31535123 = 31535182
101 + 31535081 = 31535182
149 + 31535033 = 31535182
269 + 31534913 = 31535182
311 + 31534871 = 31535182
383 + 31534799 = 31535182
431 + 31534751 = 31535182

Showing the first eight; more decompositions exist.
