Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541090, here are decompositions:

19 + 31541071 = 31541090
43 + 31541047 = 31541090
73 + 31541017 = 31541090
151 + 31540939 = 31541090
223 + 31540867 = 31541090
277 + 31540813 = 31541090
307 + 31540783 = 31541090
367 + 31540723 = 31541090

Showing the first eight; more decompositions exist.
