Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77102, here are decompositions:

61 + 77041 = 77102
73 + 77029 = 77102
79 + 77023 = 77102
139 + 76963 = 77102
229 + 76873 = 77102
271 + 76831 = 77102
283 + 76819 = 77102
331 + 76771 = 77102

Showing the first eight; more decompositions exist.
