Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475962, here are decompositions:

53 + 31475909 = 31475962
113 + 31475849 = 31475962
149 + 31475813 = 31475962
191 + 31475771 = 31475962
281 + 31475681 = 31475962
293 + 31475669 = 31475962
383 + 31475579 = 31475962
491 + 31475471 = 31475962

Showing the first eight; more decompositions exist.
