Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553592, here are decompositions:

73 + 31553519 = 31553592
89 + 31553503 = 31553592
139 + 31553453 = 31553592
223 + 31553369 = 31553592
233 + 31553359 = 31553592
241 + 31553351 = 31553592
271 + 31553321 = 31553592
313 + 31553279 = 31553592

Showing the first eight; more decompositions exist.
