Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460876, here are decompositions:

3 + 31460873 = 31460876
37 + 31460839 = 31460876
43 + 31460833 = 31460876
67 + 31460809 = 31460876
199 + 31460677 = 31460876
229 + 31460647 = 31460876
367 + 31460509 = 31460876
379 + 31460497 = 31460876

Showing the first eight; more decompositions exist.
