Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542372, here are decompositions:

73 + 542299 = 542372
79 + 542293 = 542372
109 + 542263 = 542372
223 + 542149 = 542372
241 + 542131 = 542372
349 + 542023 = 542372
373 + 541999 = 542372
379 + 541993 = 542372

Showing the first eight; more decompositions exist.
