Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181962, here are decompositions:

5 + 181957 = 181962
19 + 181943 = 181962
31 + 181931 = 181962
43 + 181919 = 181962
59 + 181903 = 181962
71 + 181891 = 181962
73 + 181889 = 181962
89 + 181873 = 181962

Showing the first eight; more decompositions exist.
