Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527854, here are decompositions:

37 + 31527817 = 31527854
67 + 31527787 = 31527854
73 + 31527781 = 31527854
151 + 31527703 = 31527854
157 + 31527697 = 31527854
271 + 31527583 = 31527854
277 + 31527577 = 31527854
313 + 31527541 = 31527854

Showing the first eight; more decompositions exist.
