Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72878, here are decompositions:

7 + 72871 = 72878
19 + 72859 = 72878
61 + 72817 = 72878
139 + 72739 = 72878
151 + 72727 = 72878
199 + 72679 = 72878
229 + 72649 = 72878
331 + 72547 = 72878

Showing the first eight; more decompositions exist.
