Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551754, here are decompositions:

71 + 31551683 = 31551754
83 + 31551671 = 31551754
167 + 31551587 = 31551754
251 + 31551503 = 31551754
257 + 31551497 = 31551754
293 + 31551461 = 31551754
317 + 31551437 = 31551754
347 + 31551407 = 31551754

Showing the first eight; more decompositions exist.
