Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91058, here are decompositions:

61 + 90997 = 91058
127 + 90931 = 91058
151 + 90907 = 91058
157 + 90901 = 91058
211 + 90847 = 91058
271 + 90787 = 91058
349 + 90709 = 91058
379 + 90679 = 91058

Showing the first eight; more decompositions exist.
