Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526078, here are decompositions:

97 + 31525981 = 31526078
127 + 31525951 = 31526078
151 + 31525927 = 31526078
229 + 31525849 = 31526078
307 + 31525771 = 31526078
379 + 31525699 = 31526078
421 + 31525657 = 31526078
541 + 31525537 = 31526078

Showing the first eight; more decompositions exist.
