Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488532, here are decompositions:

233 + 31488299 = 31488532
239 + 31488293 = 31488532
431 + 31488101 = 31488532
443 + 31488089 = 31488532
461 + 31488071 = 31488532
479 + 31488053 = 31488532
659 + 31487873 = 31488532
1019 + 31487513 = 31488532

Showing the first eight; more decompositions exist.
