Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541546, here are decompositions:

19 + 31541527 = 31541546
37 + 31541509 = 31541546
79 + 31541467 = 31541546
97 + 31541449 = 31541546
109 + 31541437 = 31541546
199 + 31541347 = 31541546
277 + 31541269 = 31541546
313 + 31541233 = 31541546

Showing the first eight; more decompositions exist.
