Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535734, here are decompositions:

17 + 31535717 = 31535734
53 + 31535681 = 31535734
101 + 31535633 = 31535734
311 + 31535423 = 31535734
317 + 31535417 = 31535734
353 + 31535381 = 31535734
521 + 31535213 = 31535734
563 + 31535171 = 31535734

Showing the first eight; more decompositions exist.
