Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542624, here are decompositions:

37 + 542587 = 542624
67 + 542557 = 542624
73 + 542551 = 542624
127 + 542497 = 542624
157 + 542467 = 542624
163 + 542461 = 542624
223 + 542401 = 542624
331 + 542293 = 542624

Showing the first eight; more decompositions exist.
