Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500546, here are decompositions:

17 + 31500529 = 31500546
37 + 31500509 = 31500546
43 + 31500503 = 31500546
59 + 31500487 = 31500546
83 + 31500463 = 31500546
89 + 31500457 = 31500546
127 + 31500419 = 31500546
139 + 31500407 = 31500546

Showing the first eight; more decompositions exist.
