Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554508, here are decompositions:

59 + 31554449 = 31554508
107 + 31554401 = 31554508
347 + 31554161 = 31554508
431 + 31554077 = 31554508
521 + 31553987 = 31554508
641 + 31553867 = 31554508
701 + 31553807 = 31554508
1187 + 31553321 = 31554508

Showing the first eight; more decompositions exist.
