Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642012, here are decompositions:

103 + 8641909 = 8642012
139 + 8641873 = 8642012
193 + 8641819 = 8642012
229 + 8641783 = 8642012
271 + 8641741 = 8642012
409 + 8641603 = 8642012
499 + 8641513 = 8642012
541 + 8641471 = 8642012

Showing the first eight; more decompositions exist.
