Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576592, here are decompositions:

13 + 31576579 = 31576592
43 + 31576549 = 31576592
109 + 31576483 = 31576592
139 + 31576453 = 31576592
181 + 31576411 = 31576592
241 + 31576351 = 31576592
331 + 31576261 = 31576592
373 + 31576219 = 31576592

Showing the first eight; more decompositions exist.
