Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488822, here are decompositions:

23 + 31488799 = 31488822
89 + 31488733 = 31488822
191 + 31488631 = 31488822
353 + 31488469 = 31488822
359 + 31488463 = 31488822
389 + 31488433 = 31488822
499 + 31488323 = 31488822
523 + 31488299 = 31488822

Showing the first eight; more decompositions exist.
