Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78154, here are decompositions:

17 + 78137 = 78154
53 + 78101 = 78154
113 + 78041 = 78154
137 + 78017 = 78154
353 + 77801 = 78154
431 + 77723 = 78154
443 + 77711 = 78154
467 + 77687 = 78154

Showing the first eight; more decompositions exist.
