Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42746, here are decompositions:

3 + 42743 = 42746
19 + 42727 = 42746
37 + 42709 = 42746
43 + 42703 = 42746
79 + 42667 = 42746
97 + 42649 = 42746
103 + 42643 = 42746
157 + 42589 = 42746

Showing the first eight; more decompositions exist.
