Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483132, here are decompositions:

71 + 31483061 = 31483132
293 + 31482839 = 31483132
311 + 31482821 = 31483132
353 + 31482779 = 31483132
389 + 31482743 = 31483132
449 + 31482683 = 31483132
491 + 31482641 = 31483132
563 + 31482569 = 31483132

Showing the first eight; more decompositions exist.
