Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609346, here are decompositions:

7 + 31609339 = 31609346
79 + 31609267 = 31609346
157 + 31609189 = 31609346
229 + 31609117 = 31609346
313 + 31609033 = 31609346
409 + 31608937 = 31609346
463 + 31608883 = 31609346
523 + 31608823 = 31609346

Showing the first eight; more decompositions exist.
