Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489588, here are decompositions:

17 + 31489571 = 31489588
47 + 31489541 = 31489588
197 + 31489391 = 31489588
239 + 31489349 = 31489588
359 + 31489229 = 31489588
419 + 31489169 = 31489588
491 + 31489097 = 31489588
509 + 31489079 = 31489588

Showing the first eight; more decompositions exist.
