Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148742, here are decompositions:

19 + 148723 = 148742
31 + 148711 = 148742
73 + 148669 = 148742
79 + 148663 = 148742
103 + 148639 = 148742
109 + 148633 = 148742
163 + 148579 = 148742
193 + 148549 = 148742

Showing the first eight; more decompositions exist.
