Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547398, here are decompositions:

41 + 31547357 = 31547398
59 + 31547339 = 31547398
101 + 31547297 = 31547398
131 + 31547267 = 31547398
137 + 31547261 = 31547398
167 + 31547231 = 31547398
251 + 31547147 = 31547398
269 + 31547129 = 31547398

Showing the first eight; more decompositions exist.
