Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148722, here are decompositions:

11 + 148711 = 148722
29 + 148693 = 148722
31 + 148691 = 148722
53 + 148669 = 148722
59 + 148663 = 148722
83 + 148639 = 148722
89 + 148633 = 148722
113 + 148609 = 148722

Showing the first eight; more decompositions exist.
