Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589534, here are decompositions:

61 + 31589473 = 31589534
73 + 31589461 = 31589534
127 + 31589407 = 31589534
157 + 31589377 = 31589534
181 + 31589353 = 31589534
241 + 31589293 = 31589534
283 + 31589251 = 31589534
337 + 31589197 = 31589534

Showing the first eight; more decompositions exist.
