Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589452, here are decompositions:

29 + 31589423 = 31589452
113 + 31589339 = 31589452
131 + 31589321 = 31589452
149 + 31589303 = 31589452
269 + 31589183 = 31589452
353 + 31589099 = 31589452
383 + 31589069 = 31589452
509 + 31588943 = 31589452

Showing the first eight; more decompositions exist.
