Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583024, here are decompositions:

43 + 31582981 = 31583024
73 + 31582951 = 31583024
127 + 31582897 = 31583024
397 + 31582627 = 31583024
607 + 31582417 = 31583024
691 + 31582333 = 31583024
757 + 31582267 = 31583024
853 + 31582171 = 31583024

Showing the first eight; more decompositions exist.
