Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78224, here are decompositions:

31 + 78193 = 78224
61 + 78163 = 78224
67 + 78157 = 78224
103 + 78121 = 78224
193 + 78031 = 78224
241 + 77983 = 78224
331 + 77893 = 78224
463 + 77761 = 78224

Showing the first eight; more decompositions exist.
