Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542572, here are decompositions:

5 + 542567 = 542572
53 + 542519 = 542572
83 + 542489 = 542572
89 + 542483 = 542572
131 + 542441 = 542572
311 + 542261 = 542572
353 + 542219 = 542572
383 + 542189 = 542572

Showing the first eight; more decompositions exist.
