Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527422, here are decompositions:

79 + 31527343 = 31527422
211 + 31527211 = 31527422
229 + 31527193 = 31527422
271 + 31527151 = 31527422
313 + 31527109 = 31527422
523 + 31526899 = 31527422
541 + 31526881 = 31527422
613 + 31526809 = 31527422

Showing the first eight; more decompositions exist.
