Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523426, here are decompositions:

23 + 523403 = 523426
257 + 523169 = 523426
317 + 523109 = 523426
419 + 523007 = 523426
467 + 522959 = 523426
479 + 522947 = 523426
569 + 522857 = 523426
587 + 522839 = 523426

Showing the first eight; more decompositions exist.
