Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558056, here are decompositions:

7 + 31558049 = 31558056
17 + 31558039 = 31558056
37 + 31558019 = 31558056
43 + 31558013 = 31558056
59 + 31557997 = 31558056
73 + 31557983 = 31558056
97 + 31557959 = 31558056
137 + 31557919 = 31558056

Showing the first eight; more decompositions exist.
