Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547562, here are decompositions:

5 + 31547557 = 31547562
23 + 31547539 = 31547562
31 + 31547531 = 31547562
43 + 31547519 = 31547562
73 + 31547489 = 31547562
83 + 31547479 = 31547562
103 + 31547459 = 31547562
113 + 31547449 = 31547562

Showing the first eight; more decompositions exist.
