Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527908, here are decompositions:

79 + 31527829 = 31527908
127 + 31527781 = 31527908
199 + 31527709 = 31527908
211 + 31527697 = 31527908
331 + 31527577 = 31527908
367 + 31527541 = 31527908
409 + 31527499 = 31527908
631 + 31527277 = 31527908

Showing the first eight; more decompositions exist.
