Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472046, here are decompositions:

5 + 31472041 = 31472046
17 + 31472029 = 31472046
43 + 31472003 = 31472046
79 + 31471967 = 31472046
107 + 31471939 = 31472046
113 + 31471933 = 31472046
139 + 31471907 = 31472046
163 + 31471883 = 31472046

Showing the first eight; more decompositions exist.
