Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90904, here are decompositions:

3 + 90901 = 90904
17 + 90887 = 90904
41 + 90863 = 90904
71 + 90833 = 90904
83 + 90821 = 90904
101 + 90803 = 90904
173 + 90731 = 90904
227 + 90677 = 90904

Showing the first eight; more decompositions exist.
