Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459194, here are decompositions:

43 + 31459151 = 31459194
61 + 31459133 = 31459194
71 + 31459123 = 31459194
83 + 31459111 = 31459194
101 + 31459093 = 31459194
131 + 31459063 = 31459194
163 + 31459031 = 31459194
211 + 31458983 = 31459194

Showing the first eight; more decompositions exist.
