Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515192, here are decompositions:

19 + 515173 = 515192
43 + 515149 = 515192
103 + 515089 = 515192
151 + 515041 = 515192
373 + 514819 = 515192
409 + 514783 = 515192
523 + 514669 = 515192
541 + 514651 = 515192

Showing the first eight; more decompositions exist.
