Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152730, here are decompositions:

7 + 152723 = 152730
13 + 152717 = 152730
59 + 152671 = 152730
73 + 152657 = 152730
89 + 152641 = 152730
101 + 152629 = 152730
107 + 152623 = 152730
113 + 152617 = 152730

Showing the first eight; more decompositions exist.
