Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547496, here are decompositions:

7 + 31547489 = 31547496
17 + 31547479 = 31547496
37 + 31547459 = 31547496
47 + 31547449 = 31547496
83 + 31547413 = 31547496
139 + 31547357 = 31547496
157 + 31547339 = 31547496
179 + 31547317 = 31547496

Showing the first eight; more decompositions exist.
