Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020742, here are decompositions:

53 + 1020689 = 1020742
59 + 1020683 = 1020742
251 + 1020491 = 1020742
311 + 1020431 = 1020742
353 + 1020389 = 1020742
389 + 1020353 = 1020742
449 + 1020293 = 1020742
509 + 1020233 = 1020742

Showing the first eight; more decompositions exist.
