Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532438, here are decompositions:

37 + 31532401 = 31532438
97 + 31532341 = 31532438
109 + 31532329 = 31532438
211 + 31532227 = 31532438
229 + 31532209 = 31532438
271 + 31532167 = 31532438
349 + 31532089 = 31532438
367 + 31532071 = 31532438

Showing the first eight; more decompositions exist.
