Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615832, here are decompositions:

103 + 31615729 = 31615832
163 + 31615669 = 31615832
181 + 31615651 = 31615832
223 + 31615609 = 31615832
229 + 31615603 = 31615832
349 + 31615483 = 31615832
433 + 31615399 = 31615832
499 + 31615333 = 31615832

Showing the first eight; more decompositions exist.
