Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 543242, here are decompositions:

19 + 543223 = 543242
79 + 543163 = 543242
103 + 543139 = 543242
181 + 543061 = 543242
223 + 543019 = 543242
331 + 542911 = 543242
421 + 542821 = 543242
523 + 542719 = 543242

Showing the first eight; more decompositions exist.
