Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499534, here are decompositions:

37 + 31499497 = 31499534
43 + 31499491 = 31499534
67 + 31499467 = 31499534
103 + 31499431 = 31499534
127 + 31499407 = 31499534
151 + 31499383 = 31499534
163 + 31499371 = 31499534
193 + 31499341 = 31499534

Showing the first eight; more decompositions exist.
