Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523542, here are decompositions:

23 + 523519 = 523542
31 + 523511 = 523542
53 + 523489 = 523542
79 + 523463 = 523542
83 + 523459 = 523542
109 + 523433 = 523542
139 + 523403 = 523542
191 + 523351 = 523542

Showing the first eight; more decompositions exist.
