Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020148, here are decompositions:

5 + 1020143 = 1020148
11 + 1020137 = 1020148
47 + 1020101 = 1020148
71 + 1020077 = 1020148
89 + 1020059 = 1020148
137 + 1020011 = 1020148
347 + 1019801 = 1020148
401 + 1019747 = 1020148

Showing the first eight; more decompositions exist.
