Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580592, here are decompositions:

53 + 31580539 = 31580592
61 + 31580531 = 31580592
89 + 31580503 = 31580592
139 + 31580453 = 31580592
181 + 31580411 = 31580592
223 + 31580369 = 31580592
269 + 31580323 = 31580592
271 + 31580321 = 31580592

Showing the first eight; more decompositions exist.
