Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580652, here are decompositions:

31 + 31580621 = 31580652
113 + 31580539 = 31580652
149 + 31580503 = 31580652
151 + 31580501 = 31580652
199 + 31580453 = 31580652
241 + 31580411 = 31580652
283 + 31580369 = 31580652
331 + 31580321 = 31580652

Showing the first eight; more decompositions exist.
