Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535212, here are decompositions:

29 + 31535183 = 31535212
41 + 31535171 = 31535212
89 + 31535123 = 31535212
131 + 31535081 = 31535212
179 + 31535033 = 31535212
251 + 31534961 = 31535212
461 + 31534751 = 31535212
503 + 31534709 = 31535212

Showing the first eight; more decompositions exist.
