Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554076, here are decompositions:

3 + 31554073 = 31554076
83 + 31553993 = 31554076
89 + 31553987 = 31554076
173 + 31553903 = 31554076
269 + 31553807 = 31554076
293 + 31553783 = 31554076
317 + 31553759 = 31554076
347 + 31553729 = 31554076

Showing the first eight; more decompositions exist.
