Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77236, here are decompositions:

23 + 77213 = 77236
83 + 77153 = 77236
167 + 77069 = 77236
233 + 77003 = 77236
293 + 76943 = 77236
317 + 76919 = 77236
353 + 76883 = 77236
389 + 76847 = 77236

Showing the first eight; more decompositions exist.
