Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459136, here are decompositions:

3 + 31459133 = 31459136
13 + 31459123 = 31459136
43 + 31459093 = 31459136
67 + 31459069 = 31459136
73 + 31459063 = 31459136
199 + 31458937 = 31459136
223 + 31458913 = 31459136
229 + 31458907 = 31459136

Showing the first eight; more decompositions exist.
