Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472070, here are decompositions:

17 + 31472053 = 31472070
29 + 31472041 = 31472070
41 + 31472029 = 31472070
59 + 31472011 = 31472070
67 + 31472003 = 31472070
79 + 31471991 = 31472070
103 + 31471967 = 31472070
131 + 31471939 = 31472070

Showing the first eight; more decompositions exist.
