Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542132, here are decompositions:

13 + 542119 = 542132
61 + 542071 = 542132
79 + 542053 = 542132
109 + 542023 = 542132
139 + 541993 = 542132
181 + 541951 = 542132
373 + 541759 = 542132
421 + 541711 = 542132

Showing the first eight; more decompositions exist.
