Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615652, here are decompositions:

43 + 31615609 = 31615652
109 + 31615543 = 31615652
163 + 31615489 = 31615652
181 + 31615471 = 31615652
223 + 31615429 = 31615652
331 + 31615321 = 31615652
379 + 31615273 = 31615652
499 + 31615153 = 31615652

Showing the first eight; more decompositions exist.
