Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569424, here are decompositions:

137 + 31569287 = 31569424
167 + 31569257 = 31569424
191 + 31569233 = 31569424
317 + 31569107 = 31569424
503 + 31568921 = 31569424
701 + 31568723 = 31569424
863 + 31568561 = 31569424
881 + 31568543 = 31569424

Showing the first eight; more decompositions exist.
