Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977180, here are decompositions:

13 + 977167 = 977180
31 + 977149 = 977180
73 + 977107 = 977180
157 + 977023 = 977180
223 + 976957 = 977180
229 + 976951 = 977180
271 + 976909 = 977180
331 + 976849 = 977180

Showing the first eight; more decompositions exist.
