Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494048, here are decompositions:

7 + 31494041 = 31494048
59 + 31493989 = 31494048
97 + 31493951 = 31494048
107 + 31493941 = 31494048
139 + 31493909 = 31494048
149 + 31493899 = 31494048
167 + 31493881 = 31494048
191 + 31493857 = 31494048

Showing the first eight; more decompositions exist.
