Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555654, here are decompositions:

3 + 31555651 = 31555654
23 + 31555631 = 31555654
47 + 31555607 = 31555654
83 + 31555571 = 31555654
113 + 31555541 = 31555654
401 + 31555253 = 31555654
443 + 31555211 = 31555654
467 + 31555187 = 31555654

Showing the first eight; more decompositions exist.
