Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91042, here are decompositions:

23 + 91019 = 91042
53 + 90989 = 91042
71 + 90971 = 91042
131 + 90911 = 91042
179 + 90863 = 91042
239 + 90803 = 91042
293 + 90749 = 91042
311 + 90731 = 91042

Showing the first eight; more decompositions exist.
