Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78222, here are decompositions:

19 + 78203 = 78222
29 + 78193 = 78222
31 + 78191 = 78222
43 + 78179 = 78222
59 + 78163 = 78222
83 + 78139 = 78222
101 + 78121 = 78222
163 + 78059 = 78222

Showing the first eight; more decompositions exist.
