Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530694, here are decompositions:

11 + 31530683 = 31530694
53 + 31530641 = 31530694
101 + 31530593 = 31530694
197 + 31530497 = 31530694
257 + 31530437 = 31530694
311 + 31530383 = 31530694
317 + 31530377 = 31530694
347 + 31530347 = 31530694

Showing the first eight; more decompositions exist.
