Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 524780, here are decompositions:

37 + 524743 = 524780
73 + 524707 = 524780
79 + 524701 = 524780
97 + 524683 = 524780
181 + 524599 = 524780
271 + 524509 = 524780
283 + 524497 = 524780
367 + 524413 = 524780

Showing the first eight; more decompositions exist.
