Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562612, here are decompositions:

19 + 31562593 = 31562612
61 + 31562551 = 31562612
163 + 31562449 = 31562612
181 + 31562431 = 31562612
223 + 31562389 = 31562612
283 + 31562329 = 31562612
313 + 31562299 = 31562612
331 + 31562281 = 31562612

Showing the first eight; more decompositions exist.
