Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020158, here are decompositions:

79 + 1020079 = 1020158
109 + 1020049 = 1020158
151 + 1020007 = 1020158
157 + 1020001 = 1020158
331 + 1019827 = 1020158
457 + 1019701 = 1020158
541 + 1019617 = 1020158
691 + 1019467 = 1020158

Showing the first eight; more decompositions exist.
