Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482544, here are decompositions:

251 + 31482293 = 31482544
263 + 31482281 = 31482544
461 + 31482083 = 31482544
503 + 31482041 = 31482544
563 + 31481981 = 31482544
593 + 31481951 = 31482544
677 + 31481867 = 31482544
701 + 31481843 = 31482544

Showing the first eight; more decompositions exist.
