Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589458, here are decompositions:

137 + 31589321 = 31589458
167 + 31589291 = 31589458
359 + 31589099 = 31589458
389 + 31589069 = 31589458
401 + 31589057 = 31589458
431 + 31589027 = 31589458
479 + 31588979 = 31589458
827 + 31588631 = 31589458

Showing the first eight; more decompositions exist.
