Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90520, here are decompositions:

47 + 90473 = 90520
83 + 90437 = 90520
113 + 90407 = 90520
149 + 90371 = 90520
167 + 90353 = 90520
239 + 90281 = 90520
257 + 90263 = 90520
281 + 90239 = 90520

Showing the first eight; more decompositions exist.
