Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042180, here are decompositions:

47 + 1042133 = 1042180
59 + 1042121 = 1042180
71 + 1042109 = 1042180
89 + 1042091 = 1042180
137 + 1042043 = 1042180
179 + 1042001 = 1042180
197 + 1041983 = 1042180
311 + 1041869 = 1042180

Showing the first eight; more decompositions exist.
