Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521368, here are decompositions:

5 + 521363 = 521368
11 + 521357 = 521368
59 + 521309 = 521368
101 + 521267 = 521368
137 + 521231 = 521368
167 + 521201 = 521368
191 + 521177 = 521368
317 + 521051 = 521368

Showing the first eight; more decompositions exist.
