Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509934, here are decompositions:

41 + 31509893 = 31509934
83 + 31509851 = 31509934
173 + 31509761 = 31509934
251 + 31509683 = 31509934
293 + 31509641 = 31509934
317 + 31509617 = 31509934
503 + 31509431 = 31509934
563 + 31509371 = 31509934

Showing the first eight; more decompositions exist.
