Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609526, here are decompositions:

7 + 31609519 = 31609526
73 + 31609453 = 31609526
313 + 31609213 = 31609526
337 + 31609189 = 31609526
409 + 31609117 = 31609526
433 + 31609093 = 31609526
439 + 31609087 = 31609526
643 + 31608883 = 31609526

Showing the first eight; more decompositions exist.
