Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500434, here are decompositions:

67 + 31500367 = 31500434
73 + 31500361 = 31500434
241 + 31500193 = 31500434
541 + 31499893 = 31500434
571 + 31499863 = 31500434
601 + 31499833 = 31500434
631 + 31499803 = 31500434
673 + 31499761 = 31500434

Showing the first eight; more decompositions exist.
