Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554248, here are decompositions:

7 + 31554241 = 31554248
67 + 31554181 = 31554248
127 + 31554121 = 31554248
487 + 31553761 = 31554248
541 + 31553707 = 31554248
577 + 31553671 = 31554248
631 + 31553617 = 31554248
1087 + 31553161 = 31554248

Showing the first eight; more decompositions exist.
