Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731022, here are decompositions:

73 + 8730949 = 8731022
103 + 8730919 = 8731022
109 + 8730913 = 8731022
163 + 8730859 = 8731022
229 + 8730793 = 8731022
241 + 8730781 = 8731022
331 + 8730691 = 8731022
373 + 8730649 = 8731022

Showing the first eight; more decompositions exist.
