Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89042, here are decompositions:

73 + 88969 = 89042
139 + 88903 = 89042
181 + 88861 = 89042
199 + 88843 = 89042
223 + 88819 = 89042
229 + 88813 = 89042
241 + 88801 = 89042
271 + 88771 = 89042

Showing the first eight; more decompositions exist.
