Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472874, here are decompositions:

7 + 31472867 = 31472874
23 + 31472851 = 31472874
47 + 31472827 = 31472874
61 + 31472813 = 31472874
67 + 31472807 = 31472874
101 + 31472773 = 31472874
151 + 31472723 = 31472874
211 + 31472663 = 31472874

Showing the first eight; more decompositions exist.
