Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609592, here are decompositions:

31 + 31609561 = 31609592
43 + 31609549 = 31609592
61 + 31609531 = 31609592
73 + 31609519 = 31609592
139 + 31609453 = 31609592
199 + 31609393 = 31609592
211 + 31609381 = 31609592
379 + 31609213 = 31609592

Showing the first eight; more decompositions exist.
