Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103730, here are decompositions:

7 + 103723 = 103730
31 + 103699 = 103730
43 + 103687 = 103730
61 + 103669 = 103730
73 + 103657 = 103730
79 + 103651 = 103730
139 + 103591 = 103730
157 + 103573 = 103730

Showing the first eight; more decompositions exist.
