Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547616, here are decompositions:

7 + 31547609 = 31547616
59 + 31547557 = 31547616
97 + 31547519 = 31547616
109 + 31547507 = 31547616
127 + 31547489 = 31547616
137 + 31547479 = 31547616
157 + 31547459 = 31547616
167 + 31547449 = 31547616

Showing the first eight; more decompositions exist.
