Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542900, here are decompositions:

79 + 542821 = 542900
103 + 542797 = 542900
109 + 542791 = 542900
139 + 542761 = 542900
181 + 542719 = 542900
313 + 542587 = 542900
349 + 542551 = 542900
367 + 542533 = 542900

Showing the first eight; more decompositions exist.
