Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532612, here are decompositions:

19 + 31532593 = 31532612
31 + 31532581 = 31532612
61 + 31532551 = 31532612
73 + 31532539 = 31532612
211 + 31532401 = 31532612
271 + 31532341 = 31532612
283 + 31532329 = 31532612
409 + 31532203 = 31532612

Showing the first eight; more decompositions exist.
