Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524934, here are decompositions:

41 + 31524893 = 31524934
71 + 31524863 = 31524934
137 + 31524797 = 31524934
167 + 31524767 = 31524934
257 + 31524677 = 31524934
293 + 31524641 = 31524934
347 + 31524587 = 31524934
401 + 31524533 = 31524934

Showing the first eight; more decompositions exist.
