Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500034, here are decompositions:

11 + 31500023 = 31500034
17 + 31500017 = 31500034
101 + 31499933 = 31500034
113 + 31499921 = 31500034
191 + 31499843 = 31500034
647 + 31499387 = 31500034
743 + 31499291 = 31500034
971 + 31499063 = 31500034

Showing the first eight; more decompositions exist.
