Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543376, here are decompositions:

103 + 31543273 = 31543376
157 + 31543219 = 31543376
307 + 31543069 = 31543376
367 + 31543009 = 31543376
409 + 31542967 = 31543376
433 + 31542943 = 31543376
439 + 31542937 = 31543376
499 + 31542877 = 31543376

Showing the first eight; more decompositions exist.
