Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522578, here are decompositions:

37 + 522541 = 522578
61 + 522517 = 522578
109 + 522469 = 522578
139 + 522439 = 522578
241 + 522337 = 522578
349 + 522229 = 522578
367 + 522211 = 522578
379 + 522199 = 522578

Showing the first eight; more decompositions exist.
