Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527362, here are decompositions:

19 + 31527343 = 31527362
109 + 31527253 = 31527362
151 + 31527211 = 31527362
211 + 31527151 = 31527362
409 + 31526953 = 31527362
421 + 31526941 = 31527362
463 + 31526899 = 31527362
499 + 31526863 = 31527362

Showing the first eight; more decompositions exist.
