Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509248, here are decompositions:

101 + 509147 = 509248
317 + 508931 = 509248
347 + 508901 = 509248
401 + 508847 = 509248
431 + 508817 = 509248
449 + 508799 = 509248
521 + 508727 = 509248
587 + 508661 = 509248

Showing the first eight; more decompositions exist.
