Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642192, here are decompositions:

3 + 8642189 = 8642192
19 + 8642173 = 8642192
73 + 8642119 = 8642192
283 + 8641909 = 8642192
373 + 8641819 = 8642192
409 + 8641783 = 8642192
523 + 8641669 = 8642192
541 + 8641651 = 8642192

Showing the first eight; more decompositions exist.
