Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584358, here are decompositions:

59 + 31584299 = 31584358
167 + 31584191 = 31584358
257 + 31584101 = 31584358
359 + 31583999 = 31584358
461 + 31583897 = 31584358
521 + 31583837 = 31584358
587 + 31583771 = 31584358
761 + 31583597 = 31584358

Showing the first eight; more decompositions exist.
