Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012180, here are decompositions:

47 + 1012133 = 1012180
83 + 1012097 = 1012180
101 + 1012079 = 1012180
131 + 1012049 = 1012180
137 + 1012043 = 1012180
149 + 1012031 = 1012180
173 + 1012007 = 1012180
233 + 1011947 = 1012180

Showing the first eight; more decompositions exist.
