Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523718, here are decompositions:

37 + 523681 = 523718
61 + 523657 = 523718
79 + 523639 = 523718
199 + 523519 = 523718
229 + 523489 = 523718
331 + 523387 = 523718
367 + 523351 = 523718
421 + 523297 = 523718

Showing the first eight; more decompositions exist.
