Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487700, here are decompositions:

19 + 487681 = 487700
43 + 487657 = 487700
97 + 487603 = 487700
139 + 487561 = 487700
193 + 487507 = 487700
211 + 487489 = 487700
223 + 487477 = 487700
229 + 487471 = 487700

Showing the first eight; more decompositions exist.
