Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500554, here are decompositions:

67 + 31500487 = 31500554
97 + 31500457 = 31500554
103 + 31500451 = 31500554
193 + 31500361 = 31500554
367 + 31500187 = 31500554
661 + 31499893 = 31500554
691 + 31499863 = 31500554
751 + 31499803 = 31500554

Showing the first eight; more decompositions exist.
