Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542664, here are decompositions:

61 + 542603 = 542664
97 + 542567 = 542664
107 + 542557 = 542664
113 + 542551 = 542664
127 + 542537 = 542664
131 + 542533 = 542664
167 + 542497 = 542664
181 + 542483 = 542664

Showing the first eight; more decompositions exist.
