Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731002, here are decompositions:

19 + 8730983 = 8731002
53 + 8730949 = 8731002
73 + 8730929 = 8731002
83 + 8730919 = 8731002
89 + 8730913 = 8731002
101 + 8730901 = 8731002
109 + 8730893 = 8731002
113 + 8730889 = 8731002

Showing the first eight; more decompositions exist.
