Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582294, here are decompositions:

53 + 31582241 = 31582294
101 + 31582193 = 31582294
131 + 31582163 = 31582294
173 + 31582121 = 31582294
197 + 31582097 = 31582294
251 + 31582043 = 31582294
257 + 31582037 = 31582294
311 + 31581983 = 31582294

Showing the first eight; more decompositions exist.
