Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731452, here are decompositions:

5 + 8731447 = 8731452
19 + 8731433 = 8731452
71 + 8731381 = 8731452
83 + 8731369 = 8731452
89 + 8731363 = 8731452
109 + 8731343 = 8731452
113 + 8731339 = 8731452
131 + 8731321 = 8731452

Showing the first eight; more decompositions exist.
