Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609262, here are decompositions:

31 + 31609231 = 31609262
73 + 31609189 = 31609262
151 + 31609111 = 31609262
229 + 31609033 = 31609262
379 + 31608883 = 31609262
409 + 31608853 = 31609262
439 + 31608823 = 31609262
541 + 31608721 = 31609262

Showing the first eight; more decompositions exist.
