Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472876, here are decompositions:

37 + 31472839 = 31472876
103 + 31472773 = 31472876
397 + 31472479 = 31472876
439 + 31472437 = 31472876
709 + 31472167 = 31472876
727 + 31472149 = 31472876
733 + 31472143 = 31472876
769 + 31472107 = 31472876

Showing the first eight; more decompositions exist.
