Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712242, here are decompositions:

13 + 8712229 = 8712242
61 + 8712181 = 8712242
73 + 8712169 = 8712242
79 + 8712163 = 8712242
109 + 8712133 = 8712242
151 + 8712091 = 8712242
223 + 8712019 = 8712242
271 + 8711971 = 8712242

Showing the first eight; more decompositions exist.
