Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482144, here are decompositions:

41 + 31482103 = 31482144
47 + 31482097 = 31482144
61 + 31482083 = 31482144
97 + 31482047 = 31482144
101 + 31482043 = 31482144
103 + 31482041 = 31482144
107 + 31482037 = 31482144
131 + 31482013 = 31482144

Showing the first eight; more decompositions exist.
