Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472026, here are decompositions:

23 + 31472003 = 31472026
59 + 31471967 = 31472026
227 + 31471799 = 31472026
239 + 31471787 = 31472026
263 + 31471763 = 31472026
359 + 31471667 = 31472026
389 + 31471637 = 31472026
449 + 31471577 = 31472026

Showing the first eight; more decompositions exist.
