Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554394, here are decompositions:

107 + 31554287 = 31554394
233 + 31554161 = 31554394
251 + 31554143 = 31554394
317 + 31554077 = 31554394
383 + 31554011 = 31554394
401 + 31553993 = 31554394
491 + 31553903 = 31554394
587 + 31553807 = 31554394

Showing the first eight; more decompositions exist.
