Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180036, here are decompositions:

13 + 180023 = 180036
29 + 180007 = 180036
37 + 179999 = 180036
47 + 179989 = 180036
67 + 179969 = 180036
79 + 179957 = 180036
83 + 179953 = 180036
89 + 179947 = 180036

Showing the first eight; more decompositions exist.
