Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148860, here are decompositions:

7 + 148853 = 148860
31 + 148829 = 148860
43 + 148817 = 148860
67 + 148793 = 148860
79 + 148781 = 148860
97 + 148763 = 148860
113 + 148747 = 148860
137 + 148723 = 148860

Showing the first eight; more decompositions exist.
