Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583684, here are decompositions:

43 + 31583641 = 31583684
157 + 31583527 = 31583684
163 + 31583521 = 31583684
271 + 31583413 = 31583684
331 + 31583353 = 31583684
547 + 31583137 = 31583684
661 + 31583023 = 31583684
733 + 31582951 = 31583684

Showing the first eight; more decompositions exist.
