Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140558, here are decompositions:

7 + 140551 = 140558
31 + 140527 = 140558
37 + 140521 = 140558
109 + 140449 = 140558
139 + 140419 = 140558
151 + 140407 = 140558
157 + 140401 = 140558
241 + 140317 = 140558

Showing the first eight; more decompositions exist.
