Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459092, here are decompositions:

19 + 31459073 = 31459092
23 + 31459069 = 31459092
29 + 31459063 = 31459092
61 + 31459031 = 31459092
73 + 31459019 = 31459092
109 + 31458983 = 31459092
139 + 31458953 = 31459092
179 + 31458913 = 31459092

Showing the first eight; more decompositions exist.
