Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535058, here are decompositions:

47 + 31535011 = 31535058
59 + 31534999 = 31535058
97 + 31534961 = 31535058
179 + 31534879 = 31535058
227 + 31534831 = 31535058
239 + 31534819 = 31535058
257 + 31534801 = 31535058
271 + 31534787 = 31535058

Showing the first eight; more decompositions exist.
