Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148724, here are decompositions:

3 + 148721 = 148724
13 + 148711 = 148724
31 + 148693 = 148724
61 + 148663 = 148724
97 + 148627 = 148724
151 + 148573 = 148724
193 + 148531 = 148724
211 + 148513 = 148724

Showing the first eight; more decompositions exist.
