Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535074, here are decompositions:

17 + 31535057 = 31535074
41 + 31535033 = 31535074
113 + 31534961 = 31535074
317 + 31534757 = 31535074
383 + 31534691 = 31535074
443 + 31534631 = 31535074
521 + 31534553 = 31535074
587 + 31534487 = 31535074

Showing the first eight; more decompositions exist.
