Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 141978, here are decompositions:

7 + 141971 = 141978
17 + 141961 = 141978
19 + 141959 = 141978
37 + 141941 = 141978
41 + 141937 = 141978
47 + 141931 = 141978
61 + 141917 = 141978
71 + 141907 = 141978

Showing the first eight; more decompositions exist.
