Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504848, here are decompositions:

29 + 31504819 = 31504848
47 + 31504801 = 31504848
101 + 31504747 = 31504848
157 + 31504691 = 31504848
181 + 31504667 = 31504848
197 + 31504651 = 31504848
229 + 31504619 = 31504848
241 + 31504607 = 31504848

Showing the first eight; more decompositions exist.
