Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535152, here are decompositions:

29 + 31535123 = 31535152
71 + 31535081 = 31535152
191 + 31534961 = 31535152
239 + 31534913 = 31535152
281 + 31534871 = 31535152
353 + 31534799 = 31535152
401 + 31534751 = 31535152
443 + 31534709 = 31535152

Showing the first eight; more decompositions exist.
