Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527284, here are decompositions:

7 + 31527277 = 31527284
31 + 31527253 = 31527284
37 + 31527247 = 31527284
73 + 31527211 = 31527284
127 + 31527157 = 31527284
331 + 31526953 = 31527284
421 + 31526863 = 31527284
571 + 31526713 = 31527284

Showing the first eight; more decompositions exist.
