Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589546, here are decompositions:

7 + 31589539 = 31589546
73 + 31589473 = 31589546
139 + 31589407 = 31589546
193 + 31589353 = 31589546
229 + 31589317 = 31589546
349 + 31589197 = 31589546
379 + 31589167 = 31589546
409 + 31589137 = 31589546

Showing the first eight; more decompositions exist.
