Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542672, here are decompositions:

73 + 542599 = 542672
139 + 542533 = 542672
211 + 542461 = 542672
271 + 542401 = 542672
349 + 542323 = 542672
373 + 542299 = 542672
379 + 542293 = 542672
409 + 542263 = 542672

Showing the first eight; more decompositions exist.
