Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487100, here are decompositions:

7 + 487093 = 487100
43 + 487057 = 487100
79 + 487021 = 487100
109 + 486991 = 487100
151 + 486949 = 487100
157 + 486943 = 487100
193 + 486907 = 487100
283 + 486817 = 487100

Showing the first eight; more decompositions exist.
