Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42126, here are decompositions:

37 + 42089 = 42126
43 + 42083 = 42126
53 + 42073 = 42126
83 + 42043 = 42126
103 + 42023 = 42126
107 + 42019 = 42126
109 + 42017 = 42126
113 + 42013 = 42126

Showing the first eight; more decompositions exist.
