Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527922, here are decompositions:

233 + 31527689 = 31527922
263 + 31527659 = 31527922
353 + 31527569 = 31527922
389 + 31527533 = 31527922
401 + 31527521 = 31527922
431 + 31527491 = 31527922
509 + 31527413 = 31527922
599 + 31527323 = 31527922

Showing the first eight; more decompositions exist.
