Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180026, here are decompositions:

3 + 180023 = 180026
19 + 180007 = 180026
37 + 179989 = 180026
73 + 179953 = 180026
79 + 179947 = 180026
103 + 179923 = 180026
109 + 179917 = 180026
127 + 179899 = 180026

Showing the first eight; more decompositions exist.
