Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554496, here are decompositions:

3 + 31554493 = 31554496
23 + 31554473 = 31554496
47 + 31554449 = 31554496
317 + 31554179 = 31554496
353 + 31554143 = 31554496
419 + 31554077 = 31554496
503 + 31553993 = 31554496
509 + 31553987 = 31554496

Showing the first eight; more decompositions exist.
