Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534876, here are decompositions:

3 + 31534873 = 31534876
5 + 31534871 = 31534876
89 + 31534787 = 31534876
137 + 31534739 = 31534876
167 + 31534709 = 31534876
239 + 31534637 = 31534876
383 + 31534493 = 31534876
389 + 31534487 = 31534876

Showing the first eight; more decompositions exist.
