Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589450, here are decompositions:

43 + 31589407 = 31589450
73 + 31589377 = 31589450
97 + 31589353 = 31589450
157 + 31589293 = 31589450
163 + 31589287 = 31589450
199 + 31589251 = 31589450
283 + 31589167 = 31589450
313 + 31589137 = 31589450

Showing the first eight; more decompositions exist.
