Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488076, here are decompositions:

5 + 31488071 = 31488076
17 + 31488059 = 31488076
23 + 31488053 = 31488076
83 + 31487993 = 31488076
293 + 31487783 = 31488076
419 + 31487657 = 31488076
467 + 31487609 = 31488076
563 + 31487513 = 31488076

Showing the first eight; more decompositions exist.
