Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543346, here are decompositions:

73 + 31543273 = 31543346
103 + 31543243 = 31543346
127 + 31543219 = 31543346
139 + 31543207 = 31543346
277 + 31543069 = 31543346
337 + 31543009 = 31543346
379 + 31542967 = 31543346
397 + 31542949 = 31543346

Showing the first eight; more decompositions exist.
