Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534922, here are decompositions:

43 + 31534879 = 31534922
103 + 31534819 = 31534922
193 + 31534729 = 31534922
271 + 31534651 = 31534922
379 + 31534543 = 31534922
421 + 31534501 = 31534922
439 + 31534483 = 31534922
499 + 31534423 = 31534922

Showing the first eight; more decompositions exist.
