Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459176, here are decompositions:

43 + 31459133 = 31459176
53 + 31459123 = 31459176
83 + 31459093 = 31459176
103 + 31459073 = 31459176
107 + 31459069 = 31459176
113 + 31459063 = 31459176
157 + 31459019 = 31459176
193 + 31458983 = 31459176

Showing the first eight; more decompositions exist.
