Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591972, here are decompositions:

31 + 8591941 = 8591972
73 + 8591899 = 8591972
163 + 8591809 = 8591972
199 + 8591773 = 8591972
283 + 8591689 = 8591972
349 + 8591623 = 8591972
373 + 8591599 = 8591972
379 + 8591593 = 8591972

Showing the first eight; more decompositions exist.
