Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558734, here are decompositions:

5 + 31558729 = 31558734
17 + 31558717 = 31558734
41 + 31558693 = 31558734
61 + 31558673 = 31558734
71 + 31558663 = 31558734
101 + 31558633 = 31558734
107 + 31558627 = 31558734
127 + 31558607 = 31558734

Showing the first eight; more decompositions exist.
