Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500734, here are decompositions:

43 + 31500691 = 31500734
271 + 31500463 = 31500734
277 + 31500457 = 31500734
283 + 31500451 = 31500734
367 + 31500367 = 31500734
373 + 31500361 = 31500734
541 + 31500193 = 31500734
547 + 31500187 = 31500734

Showing the first eight; more decompositions exist.
