Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462148, here are decompositions:

7 + 31462141 = 31462148
79 + 31462069 = 31462148
127 + 31462021 = 31462148
199 + 31461949 = 31462148
229 + 31461919 = 31462148
307 + 31461841 = 31462148
331 + 31461817 = 31462148
337 + 31461811 = 31462148

Showing the first eight; more decompositions exist.
