Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527644, here are decompositions:

61 + 31527583 = 31527644
67 + 31527577 = 31527644
103 + 31527541 = 31527644
163 + 31527481 = 31527644
367 + 31527277 = 31527644
397 + 31527247 = 31527644
433 + 31527211 = 31527644
487 + 31527157 = 31527644

Showing the first eight; more decompositions exist.
