Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589702, here are decompositions:

19 + 31589683 = 31589702
43 + 31589659 = 31589702
163 + 31589539 = 31589702
229 + 31589473 = 31589702
241 + 31589461 = 31589702
349 + 31589353 = 31589702
373 + 31589329 = 31589702
409 + 31589293 = 31589702

Showing the first eight; more decompositions exist.
