Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521006, here are decompositions:

37 + 520969 = 521006
43 + 520963 = 521006
139 + 520867 = 521006
193 + 520813 = 521006
307 + 520699 = 521006
373 + 520633 = 521006
397 + 520609 = 521006
439 + 520567 = 521006

Showing the first eight; more decompositions exist.
