Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527476, here are decompositions:

199 + 31527277 = 31527476
223 + 31527253 = 31527476
229 + 31527247 = 31527476
283 + 31527193 = 31527476
367 + 31527109 = 31527476
523 + 31526953 = 31527476
577 + 31526899 = 31527476
613 + 31526863 = 31527476

Showing the first eight; more decompositions exist.
