Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 524642, here are decompositions:

43 + 524599 = 524642
229 + 524413 = 524642
373 + 524269 = 524642
421 + 524221 = 524642
439 + 524203 = 524642
523 + 524119 = 524642
571 + 524071 = 524642
673 + 523969 = 524642

Showing the first eight; more decompositions exist.
