Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542636, here are decompositions:

37 + 542599 = 542636
79 + 542557 = 542636
97 + 542539 = 542636
103 + 542533 = 542636
139 + 542497 = 542636
313 + 542323 = 542636
337 + 542299 = 542636
373 + 542263 = 542636

Showing the first eight; more decompositions exist.
