Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554346, here are decompositions:

59 + 31554287 = 31554346
167 + 31554179 = 31554346
269 + 31554077 = 31554346
353 + 31553993 = 31554346
359 + 31553987 = 31554346
443 + 31553903 = 31554346
479 + 31553867 = 31554346
563 + 31553783 = 31554346

Showing the first eight; more decompositions exist.
