Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1061578, here are decompositions:

5 + 1061573 = 1061578
17 + 1061561 = 1061578
137 + 1061441 = 1061578
281 + 1061297 = 1061578
317 + 1061261 = 1061578
389 + 1061189 = 1061578
449 + 1061129 = 1061578
461 + 1061117 = 1061578

Showing the first eight; more decompositions exist.
