Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588604, here are decompositions:

43 + 31588561 = 31588604
163 + 31588441 = 31588604
283 + 31588321 = 31588604
337 + 31588267 = 31588604
433 + 31588171 = 31588604
601 + 31588003 = 31588604
643 + 31587961 = 31588604
661 + 31587943 = 31588604

Showing the first eight; more decompositions exist.
