Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020178, here are decompositions:

41 + 1020137 = 1020178
101 + 1020077 = 1020178
167 + 1020011 = 1020178
251 + 1019927 = 1020178
317 + 1019861 = 1020178
359 + 1019819 = 1020178
431 + 1019747 = 1020178
449 + 1019729 = 1020178

Showing the first eight; more decompositions exist.
