Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459174, here are decompositions:

23 + 31459151 = 31459174
41 + 31459133 = 31459174
101 + 31459073 = 31459174
191 + 31458983 = 31459174
251 + 31458923 = 31459174
311 + 31458863 = 31459174
353 + 31458821 = 31459174
587 + 31458587 = 31459174

Showing the first eight; more decompositions exist.
