Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527788, here are decompositions:

7 + 31527781 = 31527788
79 + 31527709 = 31527788
211 + 31527577 = 31527788
307 + 31527481 = 31527788
541 + 31527247 = 31527788
577 + 31527211 = 31527788
631 + 31527157 = 31527788
907 + 31526881 = 31527788

Showing the first eight; more decompositions exist.
