Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547548, here are decompositions:

17 + 31547531 = 31547548
29 + 31547519 = 31547548
41 + 31547507 = 31547548
59 + 31547489 = 31547548
89 + 31547459 = 31547548
107 + 31547441 = 31547548
191 + 31547357 = 31547548
251 + 31547297 = 31547548

Showing the first eight; more decompositions exist.
