Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465964, here are decompositions:

73 + 31465891 = 31465964
163 + 31465801 = 31465964
223 + 31465741 = 31465964
547 + 31465417 = 31465964
601 + 31465363 = 31465964
643 + 31465321 = 31465964
787 + 31465177 = 31465964
811 + 31465153 = 31465964

Showing the first eight; more decompositions exist.
