Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523394, here are decompositions:

7 + 523387 = 523394
37 + 523357 = 523394
43 + 523351 = 523394
61 + 523333 = 523394
97 + 523297 = 523394
181 + 523213 = 523394
373 + 523021 = 523394
433 + 522961 = 523394

Showing the first eight; more decompositions exist.
