Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521098, here are decompositions:

47 + 521051 = 521098
59 + 521039 = 521098
89 + 521009 = 521098
131 + 520967 = 521098
257 + 520841 = 521098
311 + 520787 = 521098
419 + 520679 = 521098
449 + 520649 = 521098

Showing the first eight; more decompositions exist.
