Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563104, here are decompositions:

31 + 31563073 = 31563104
61 + 31563043 = 31563104
73 + 31563031 = 31563104
103 + 31563001 = 31563104
193 + 31562911 = 31563104
277 + 31562827 = 31563104
337 + 31562767 = 31563104
367 + 31562737 = 31563104

Showing the first eight; more decompositions exist.
