Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543340, here are decompositions:

67 + 31543273 = 31543340
97 + 31543243 = 31543340
109 + 31543231 = 31543340
271 + 31543069 = 31543340
331 + 31543009 = 31543340
349 + 31542991 = 31543340
373 + 31542967 = 31543340
397 + 31542943 = 31543340

Showing the first eight; more decompositions exist.
