Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555704, here are decompositions:

7 + 31555697 = 31555704
41 + 31555663 = 31555704
43 + 31555661 = 31555704
53 + 31555651 = 31555704
71 + 31555633 = 31555704
73 + 31555631 = 31555704
97 + 31555607 = 31555704
101 + 31555603 = 31555704

Showing the first eight; more decompositions exist.
