Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642132, here are decompositions:

13 + 8642119 = 8642132
73 + 8642059 = 8642132
223 + 8641909 = 8642132
241 + 8641891 = 8642132
313 + 8641819 = 8642132
349 + 8641783 = 8642132
463 + 8641669 = 8642132
613 + 8641519 = 8642132

Showing the first eight; more decompositions exist.
