Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15730, here are decompositions:

3 + 15727 = 15730
47 + 15683 = 15730
59 + 15671 = 15730
83 + 15647 = 15730
89 + 15641 = 15730
101 + 15629 = 15730
149 + 15581 = 15730
179 + 15551 = 15730

Showing the first eight; more decompositions exist.
