Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159730, here are decompositions:

23 + 159707 = 159730
29 + 159701 = 159730
47 + 159683 = 159730
59 + 159671 = 159730
101 + 159629 = 159730
107 + 159623 = 159730
113 + 159617 = 159730
167 + 159563 = 159730

Showing the first eight; more decompositions exist.
