Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977148, here are decompositions:

41 + 977107 = 977148
61 + 977087 = 977148
79 + 977069 = 977148
101 + 977047 = 977148
127 + 977021 = 977148
157 + 976991 = 977148
191 + 976957 = 977148
197 + 976951 = 977148

Showing the first eight; more decompositions exist.
