Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488682, here are decompositions:

311 + 31488371 = 31488682
353 + 31488329 = 31488682
359 + 31488323 = 31488682
383 + 31488299 = 31488682
389 + 31488293 = 31488682
479 + 31488203 = 31488682
521 + 31488161 = 31488682
593 + 31488089 = 31488682

Showing the first eight; more decompositions exist.
