Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588346, here are decompositions:

43 + 31588303 = 31588346
79 + 31588267 = 31588346
367 + 31587979 = 31588346
397 + 31587949 = 31588346
487 + 31587859 = 31588346
547 + 31587799 = 31588346
919 + 31587427 = 31588346
1123 + 31587223 = 31588346

Showing the first eight; more decompositions exist.
