Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77150, here are decompositions:

13 + 77137 = 77150
103 + 77047 = 77150
109 + 77041 = 77150
127 + 77023 = 77150
277 + 76873 = 77150
313 + 76837 = 77150
331 + 76819 = 77150
349 + 76801 = 77150

Showing the first eight; more decompositions exist.
