Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471300, here are decompositions:

11 + 31471289 = 31471300
83 + 31471217 = 31471300
191 + 31471109 = 31471300
257 + 31471043 = 31471300
269 + 31471031 = 31471300
293 + 31471007 = 31471300
347 + 31470953 = 31471300
359 + 31470941 = 31471300

Showing the first eight; more decompositions exist.
