Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488034, here are decompositions:

3 + 31488031 = 31488034
41 + 31487993 = 31488034
167 + 31487867 = 31488034
251 + 31487783 = 31488034
353 + 31487681 = 31488034
491 + 31487543 = 31488034
521 + 31487513 = 31488034
563 + 31487471 = 31488034

Showing the first eight; more decompositions exist.
