Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90878, here are decompositions:

31 + 90847 = 90878
37 + 90841 = 90878
181 + 90697 = 90878
199 + 90679 = 90878
331 + 90547 = 90878
349 + 90529 = 90878
367 + 90511 = 90878
379 + 90499 = 90878

Showing the first eight; more decompositions exist.
