Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510084, here are decompositions:

5 + 31510079 = 31510084
83 + 31510001 = 31510084
113 + 31509971 = 31510084
191 + 31509893 = 31510084
233 + 31509851 = 31510084
293 + 31509791 = 31510084
311 + 31509773 = 31510084
401 + 31509683 = 31510084

Showing the first eight; more decompositions exist.
