Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589434, here are decompositions:

11 + 31589423 = 31589434
101 + 31589333 = 31589434
113 + 31589321 = 31589434
131 + 31589303 = 31589434
137 + 31589297 = 31589434
251 + 31589183 = 31589434
347 + 31589087 = 31589434
491 + 31588943 = 31589434

Showing the first eight; more decompositions exist.
