Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90804, here are decompositions:

11 + 90793 = 90804
17 + 90787 = 90804
73 + 90731 = 90804
101 + 90703 = 90804
107 + 90697 = 90804
127 + 90677 = 90804
157 + 90647 = 90804
163 + 90641 = 90804

Showing the first eight; more decompositions exist.
