Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77312, here are decompositions:

43 + 77269 = 77312
73 + 77239 = 77312
211 + 77101 = 77312
271 + 77041 = 77312
283 + 77029 = 77312
349 + 76963 = 77312
439 + 76873 = 77312
541 + 76771 = 77312

Showing the first eight; more decompositions exist.
