Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90786, here are decompositions:

37 + 90749 = 90786
83 + 90703 = 90786
89 + 90697 = 90786
107 + 90679 = 90786
109 + 90677 = 90786
127 + 90659 = 90786
139 + 90647 = 90786
167 + 90619 = 90786

Showing the first eight; more decompositions exist.
