Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521614, here are decompositions:

11 + 521603 = 521614
47 + 521567 = 521614
131 + 521483 = 521614
167 + 521447 = 521614
251 + 521363 = 521614
257 + 521357 = 521614
347 + 521267 = 521614
383 + 521231 = 521614

Showing the first eight; more decompositions exist.
