Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509526, here are decompositions:

5 + 509521 = 509526
13 + 509513 = 509526
97 + 509429 = 509526
109 + 509417 = 509526
113 + 509413 = 509526
137 + 509389 = 509526
163 + 509363 = 509526
167 + 509359 = 509526

Showing the first eight; more decompositions exist.
