Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469140, here are decompositions:

13 + 469127 = 469140
19 + 469121 = 469140
41 + 469099 = 469140
71 + 469069 = 469140
103 + 469037 = 469140
109 + 469031 = 469140
131 + 469009 = 469140
157 + 468983 = 469140

Showing the first eight; more decompositions exist.
