Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148746, here are decompositions:

19 + 148727 = 148746
23 + 148723 = 148746
53 + 148693 = 148746
79 + 148667 = 148746
83 + 148663 = 148746
107 + 148639 = 148746
113 + 148633 = 148746
137 + 148609 = 148746

Showing the first eight; more decompositions exist.
