Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588802, here are decompositions:

103 + 31588699 = 31588802
109 + 31588693 = 31588802
199 + 31588603 = 31588802
241 + 31588561 = 31588802
331 + 31588471 = 31588802
433 + 31588369 = 31588802
499 + 31588303 = 31588802
601 + 31588201 = 31588802

Showing the first eight; more decompositions exist.
