Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554226, here are decompositions:

47 + 31554179 = 31554226
83 + 31554143 = 31554226
149 + 31554077 = 31554226
233 + 31553993 = 31554226
239 + 31553987 = 31554226
359 + 31553867 = 31554226
419 + 31553807 = 31554226
443 + 31553783 = 31554226

Showing the first eight; more decompositions exist.
