Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527266, here are decompositions:

13 + 31527253 = 31527266
19 + 31527247 = 31527266
73 + 31527193 = 31527266
109 + 31527157 = 31527266
157 + 31527109 = 31527266
313 + 31526953 = 31527266
367 + 31526899 = 31527266
373 + 31526893 = 31527266

Showing the first eight; more decompositions exist.
