Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542252, here are decompositions:

103 + 542149 = 542252
181 + 542071 = 542252
199 + 542053 = 542252
229 + 542023 = 542252
421 + 541831 = 542252
541 + 541711 = 542252
673 + 541579 = 542252
709 + 541543 = 542252

Showing the first eight; more decompositions exist.
