Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572092, here are decompositions:

43 + 31572049 = 31572092
109 + 31571983 = 31572092
193 + 31571899 = 31572092
271 + 31571821 = 31572092
283 + 31571809 = 31572092
313 + 31571779 = 31572092
439 + 31571653 = 31572092
523 + 31571569 = 31572092

Showing the first eight; more decompositions exist.
