Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731330, here are decompositions:

17 + 8731313 = 8731330
29 + 8731301 = 8731330
53 + 8731277 = 8731330
191 + 8731139 = 8731330
227 + 8731103 = 8731330
233 + 8731097 = 8731330
347 + 8730983 = 8731330
353 + 8730977 = 8731330

Showing the first eight; more decompositions exist.
