Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731552, here are decompositions:

23 + 8731529 = 8731552
41 + 8731511 = 8731552
59 + 8731493 = 8731552
239 + 8731313 = 8731552
251 + 8731301 = 8731552
443 + 8731109 = 8731552
449 + 8731103 = 8731552
521 + 8731031 = 8731552

Showing the first eight; more decompositions exist.
