Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542988, here are decompositions:

7 + 542981 = 542988
37 + 542951 = 542988
41 + 542947 = 542988
67 + 542921 = 542988
97 + 542891 = 542988
151 + 542837 = 542988
157 + 542831 = 542988
167 + 542821 = 542988

Showing the first eight; more decompositions exist.
