Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727422, here are decompositions:

73 + 8727349 = 8727422
79 + 8727343 = 8727422
139 + 8727283 = 8727422
211 + 8727211 = 8727422
313 + 8727109 = 8727422
331 + 8727091 = 8727422
373 + 8727049 = 8727422
433 + 8726989 = 8727422

Showing the first eight; more decompositions exist.
