Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611344, here are decompositions:

3 + 31611341 = 31611344
43 + 31611301 = 31611344
73 + 31611271 = 31611344
157 + 31611187 = 31611344
181 + 31611163 = 31611344
277 + 31611067 = 31611344
307 + 31611037 = 31611344
433 + 31610911 = 31611344

Showing the first eight; more decompositions exist.
