Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527616, here are decompositions:

47 + 31527569 = 31527616
83 + 31527533 = 31527616
227 + 31527389 = 31527616
293 + 31527323 = 31527616
383 + 31527233 = 31527616
443 + 31527173 = 31527616
467 + 31527149 = 31527616
509 + 31527107 = 31527616

Showing the first eight; more decompositions exist.
