Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 543442, here are decompositions:

59 + 543383 = 543442
83 + 543359 = 543442
89 + 543353 = 543442
101 + 543341 = 543442
131 + 543311 = 543442
239 + 543203 = 543442
281 + 543161 = 543442
293 + 543149 = 543442

Showing the first eight; more decompositions exist.
