Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523592, here are decompositions:

13 + 31523579 = 31523592
53 + 31523539 = 31523592
71 + 31523521 = 31523592
131 + 31523461 = 31523592
151 + 31523441 = 31523592
173 + 31523419 = 31523592
181 + 31523411 = 31523592
193 + 31523399 = 31523592

Showing the first eight; more decompositions exist.
