Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558760, here are decompositions:

19 + 31558741 = 31558760
31 + 31558729 = 31558760
43 + 31558717 = 31558760
67 + 31558693 = 31558760
97 + 31558663 = 31558760
127 + 31558633 = 31558760
193 + 31558567 = 31558760
241 + 31558519 = 31558760

Showing the first eight; more decompositions exist.
