Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554436, here are decompositions:

3 + 31554433 = 31554436
149 + 31554287 = 31554436
257 + 31554179 = 31554436
293 + 31554143 = 31554436
359 + 31554077 = 31554436
443 + 31553993 = 31554436
449 + 31553987 = 31554436
569 + 31553867 = 31554436

Showing the first eight; more decompositions exist.
