Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459152, here are decompositions:

19 + 31459133 = 31459152
29 + 31459123 = 31459152
41 + 31459111 = 31459152
59 + 31459093 = 31459152
79 + 31459073 = 31459152
83 + 31459069 = 31459152
89 + 31459063 = 31459152
199 + 31458953 = 31459152

Showing the first eight; more decompositions exist.
