Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542680, here are decompositions:

101 + 542579 = 542680
113 + 542567 = 542680
191 + 542489 = 542680
197 + 542483 = 542680
233 + 542447 = 542680
239 + 542441 = 542680
419 + 542261 = 542680
443 + 542237 = 542680

Showing the first eight; more decompositions exist.
