Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499434, here are decompositions:

3 + 31499431 = 31499434
23 + 31499411 = 31499434
47 + 31499387 = 31499434
107 + 31499327 = 31499434
137 + 31499297 = 31499434
167 + 31499267 = 31499434
251 + 31499183 = 31499434
401 + 31499033 = 31499434

Showing the first eight; more decompositions exist.
