Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487924, here are decompositions:

113 + 487811 = 487924
131 + 487793 = 487924
167 + 487757 = 487924
191 + 487733 = 487924
197 + 487727 = 487924
233 + 487691 = 487924
317 + 487607 = 487924
443 + 487481 = 487924

Showing the first eight; more decompositions exist.
