Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148842, here are decompositions:

13 + 148829 = 148842
59 + 148783 = 148842
61 + 148781 = 148842
79 + 148763 = 148842
131 + 148711 = 148842
149 + 148693 = 148842
151 + 148691 = 148842
173 + 148669 = 148842

Showing the first eight; more decompositions exist.
