Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583654, here are decompositions:

13 + 31583641 = 31583654
127 + 31583527 = 31583654
241 + 31583413 = 31583654
331 + 31583323 = 31583654
373 + 31583281 = 31583654
397 + 31583257 = 31583654
523 + 31583131 = 31583654
607 + 31583047 = 31583654

Showing the first eight; more decompositions exist.
