Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609226, here are decompositions:

3 + 31609223 = 31609226
13 + 31609213 = 31609226
37 + 31609189 = 31609226
109 + 31609117 = 31609226
139 + 31609087 = 31609226
193 + 31609033 = 31609226
373 + 31608853 = 31609226
409 + 31608817 = 31609226

Showing the first eight; more decompositions exist.
