Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459162, here are decompositions:

11 + 31459151 = 31459162
29 + 31459133 = 31459162
89 + 31459073 = 31459162
131 + 31459031 = 31459162
179 + 31458983 = 31459162
239 + 31458923 = 31459162
401 + 31458761 = 31459162
443 + 31458719 = 31459162

Showing the first eight; more decompositions exist.
