Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459236, here are decompositions:

13 + 31459223 = 31459236
19 + 31459217 = 31459236
37 + 31459199 = 31459236
103 + 31459133 = 31459236
113 + 31459123 = 31459236
163 + 31459073 = 31459236
167 + 31459069 = 31459236
173 + 31459063 = 31459236

Showing the first eight; more decompositions exist.
