Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589502, here are decompositions:

19 + 31589483 = 31589502
29 + 31589473 = 31589502
41 + 31589461 = 31589502
79 + 31589423 = 31589502
101 + 31589401 = 31589502
149 + 31589353 = 31589502
163 + 31589339 = 31589502
173 + 31589329 = 31589502

Showing the first eight; more decompositions exist.
