Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459300, here are decompositions:

11 + 31459289 = 31459300
83 + 31459217 = 31459300
101 + 31459199 = 31459300
149 + 31459151 = 31459300
167 + 31459133 = 31459300
227 + 31459073 = 31459300
269 + 31459031 = 31459300
281 + 31459019 = 31459300

Showing the first eight; more decompositions exist.
