Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148712, here are decompositions:

19 + 148693 = 148712
43 + 148669 = 148712
73 + 148639 = 148712
79 + 148633 = 148712
103 + 148609 = 148712
139 + 148573 = 148712
163 + 148549 = 148712
181 + 148531 = 148712

Showing the first eight; more decompositions exist.
