Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527482, here are decompositions:

139 + 31527343 = 31527482
229 + 31527253 = 31527482
271 + 31527211 = 31527482
331 + 31527151 = 31527482
373 + 31527109 = 31527482
541 + 31526941 = 31527482
601 + 31526881 = 31527482
619 + 31526863 = 31527482

Showing the first eight; more decompositions exist.
