Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731230, here are decompositions:

17 + 8731213 = 8731230
19 + 8731211 = 8731230
29 + 8731201 = 8731230
43 + 8731187 = 8731230
89 + 8731141 = 8731230
127 + 8731103 = 8731230
191 + 8731039 = 8731230
199 + 8731031 = 8731230

Showing the first eight; more decompositions exist.
