Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583144, here are decompositions:

7 + 31583137 = 31583144
13 + 31583131 = 31583144
97 + 31583047 = 31583144
163 + 31582981 = 31583144
193 + 31582951 = 31583144
367 + 31582777 = 31583144
613 + 31582531 = 31583144
631 + 31582513 = 31583144

Showing the first eight; more decompositions exist.
