Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472066, here are decompositions:

13 + 31472053 = 31472066
37 + 31472029 = 31472066
127 + 31471939 = 31472066
433 + 31471633 = 31472066
487 + 31471579 = 31472066
709 + 31471357 = 31472066
853 + 31471213 = 31472066
859 + 31471207 = 31472066

Showing the first eight; more decompositions exist.
