Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627844, here are decompositions:

43 + 31627801 = 31627844
271 + 31627573 = 31627844
277 + 31627567 = 31627844
307 + 31627537 = 31627844
433 + 31627411 = 31627844
487 + 31627357 = 31627844
541 + 31627303 = 31627844
601 + 31627243 = 31627844

Showing the first eight; more decompositions exist.
