Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532636, here are decompositions:

43 + 31532593 = 31532636
97 + 31532539 = 31532636
139 + 31532497 = 31532636
199 + 31532437 = 31532636
283 + 31532353 = 31532636
307 + 31532329 = 31532636
313 + 31532323 = 31532636
367 + 31532269 = 31532636

Showing the first eight; more decompositions exist.
