Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480876, here are decompositions:

3 + 31480873 = 31480876
47 + 31480829 = 31480876
83 + 31480793 = 31480876
107 + 31480769 = 31480876
113 + 31480763 = 31480876
227 + 31480649 = 31480876
347 + 31480529 = 31480876
443 + 31480433 = 31480876

Showing the first eight; more decompositions exist.
