Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555734, here are decompositions:

17 + 31555717 = 31555734
37 + 31555697 = 31555734
71 + 31555663 = 31555734
73 + 31555661 = 31555734
83 + 31555651 = 31555734
101 + 31555633 = 31555734
103 + 31555631 = 31555734
127 + 31555607 = 31555734

Showing the first eight; more decompositions exist.
