Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554754, here are decompositions:

5 + 31554749 = 31554754
83 + 31554671 = 31554754
113 + 31554641 = 31554754
137 + 31554617 = 31554754
227 + 31554527 = 31554754
281 + 31554473 = 31554754
353 + 31554401 = 31554754
467 + 31554287 = 31554754

Showing the first eight; more decompositions exist.
