Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588848, here are decompositions:

41 + 31588807 = 31588848
139 + 31588709 = 31588848
149 + 31588699 = 31588848
191 + 31588657 = 31588848
241 + 31588607 = 31588848
409 + 31588439 = 31588848
449 + 31588399 = 31588848
479 + 31588369 = 31588848

Showing the first eight; more decompositions exist.
