Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583264, here are decompositions:

7 + 31583257 = 31583264
127 + 31583137 = 31583264
241 + 31583023 = 31583264
283 + 31582981 = 31583264
313 + 31582951 = 31583264
367 + 31582897 = 31583264
373 + 31582891 = 31583264
487 + 31582777 = 31583264

Showing the first eight; more decompositions exist.
