Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 992500, here are decompositions:

59 + 992441 = 992500
71 + 992429 = 992500
83 + 992417 = 992500
107 + 992393 = 992500
137 + 992363 = 992500
191 + 992309 = 992500
233 + 992267 = 992500
251 + 992249 = 992500

Showing the first eight; more decompositions exist.
