Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472670, here are decompositions:

7 + 31472663 = 31472670
37 + 31472633 = 31472670
59 + 31472611 = 31472670
79 + 31472591 = 31472670
83 + 31472587 = 31472670
181 + 31472489 = 31472670
191 + 31472479 = 31472670
233 + 31472437 = 31472670

Showing the first eight; more decompositions exist.
