Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554082, here are decompositions:

5 + 31554077 = 31554082
71 + 31554011 = 31554082
89 + 31553993 = 31554082
179 + 31553903 = 31554082
281 + 31553801 = 31554082
353 + 31553729 = 31554082
419 + 31553663 = 31554082
563 + 31553519 = 31554082

Showing the first eight; more decompositions exist.
