Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615562, here are decompositions:

19 + 31615543 = 31615562
73 + 31615489 = 31615562
79 + 31615483 = 31615562
163 + 31615399 = 31615562
229 + 31615333 = 31615562
241 + 31615321 = 31615562
409 + 31615153 = 31615562
499 + 31615063 = 31615562

Showing the first eight; more decompositions exist.
