Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532444, here are decompositions:

7 + 31532437 = 31532444
43 + 31532401 = 31532444
103 + 31532341 = 31532444
241 + 31532203 = 31532444
277 + 31532167 = 31532444
331 + 31532113 = 31532444
373 + 31532071 = 31532444
523 + 31531921 = 31532444

Showing the first eight; more decompositions exist.
