Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521854, here are decompositions:

23 + 521831 = 521854
41 + 521813 = 521854
101 + 521753 = 521854
131 + 521723 = 521854
197 + 521657 = 521854
251 + 521603 = 521854
317 + 521537 = 521854
383 + 521471 = 521854

Showing the first eight; more decompositions exist.
