Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90820, here are decompositions:

17 + 90803 = 90820
71 + 90749 = 90820
89 + 90731 = 90820
173 + 90647 = 90820
179 + 90641 = 90820
293 + 90527 = 90820
347 + 90473 = 90820
383 + 90437 = 90820

Showing the first eight; more decompositions exist.
