Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535794, here are decompositions:

41 + 31535753 = 31535794
47 + 31535747 = 31535794
53 + 31535741 = 31535794
113 + 31535681 = 31535794
137 + 31535657 = 31535794
383 + 31535411 = 31535794
467 + 31535327 = 31535794
761 + 31535033 = 31535794

Showing the first eight; more decompositions exist.
