Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547586, here are decompositions:

29 + 31547557 = 31547586
47 + 31547539 = 31547586
67 + 31547519 = 31547586
79 + 31547507 = 31547586
97 + 31547489 = 31547586
107 + 31547479 = 31547586
127 + 31547459 = 31547586
137 + 31547449 = 31547586

Showing the first eight; more decompositions exist.
