Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543406, here are decompositions:

163 + 31543243 = 31543406
199 + 31543207 = 31543406
337 + 31543069 = 31543406
397 + 31543009 = 31543406
439 + 31542967 = 31543406
457 + 31542949 = 31543406
463 + 31542943 = 31543406
577 + 31542829 = 31543406

Showing the first eight; more decompositions exist.
