Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532498, here are decompositions:

61 + 31532437 = 31532498
97 + 31532401 = 31532498
157 + 31532341 = 31532498
229 + 31532269 = 31532498
271 + 31532227 = 31532498
331 + 31532167 = 31532498
409 + 31532089 = 31532498
577 + 31531921 = 31532498

Showing the first eight; more decompositions exist.
