Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627946, here are decompositions:

19 + 31627927 = 31627946
43 + 31627903 = 31627946
67 + 31627879 = 31627946
193 + 31627753 = 31627946
307 + 31627639 = 31627946
373 + 31627573 = 31627946
379 + 31627567 = 31627946
409 + 31627537 = 31627946

Showing the first eight; more decompositions exist.
