Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487154, here are decompositions:

43 + 487111 = 487154
61 + 487093 = 487154
97 + 487057 = 487154
103 + 487051 = 487154
163 + 486991 = 487154
211 + 486943 = 487154
337 + 486817 = 487154
373 + 486781 = 487154

Showing the first eight; more decompositions exist.
