Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731424, here are decompositions:

7 + 8731417 = 8731424
43 + 8731381 = 8731424
61 + 8731363 = 8731424
103 + 8731321 = 8731424
193 + 8731231 = 8731424
211 + 8731213 = 8731424
223 + 8731201 = 8731424
271 + 8731153 = 8731424

Showing the first eight; more decompositions exist.
