Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592964, here are decompositions:

5 + 31592959 = 31592964
17 + 31592947 = 31592964
41 + 31592923 = 31592964
43 + 31592921 = 31592964
131 + 31592833 = 31592964
167 + 31592797 = 31592964
191 + 31592773 = 31592964
281 + 31592683 = 31592964

Showing the first eight; more decompositions exist.
