Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536412, here are decompositions:

29 + 31536383 = 31536412
53 + 31536359 = 31536412
59 + 31536353 = 31536412
251 + 31536161 = 31536412
311 + 31536101 = 31536412
359 + 31536053 = 31536412
431 + 31535981 = 31536412
503 + 31535909 = 31536412

Showing the first eight; more decompositions exist.
