Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553754, here are decompositions:

47 + 31553707 = 31553754
83 + 31553671 = 31553754
137 + 31553617 = 31553754
227 + 31553527 = 31553754
251 + 31553503 = 31553754
367 + 31553387 = 31553754
433 + 31553321 = 31553754
521 + 31553233 = 31553754

Showing the first eight; more decompositions exist.
