Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547654, here are decompositions:

13 + 31547641 = 31547654
37 + 31547617 = 31547654
97 + 31547557 = 31547654
241 + 31547413 = 31547654
337 + 31547317 = 31547654
367 + 31547287 = 31547654
373 + 31547281 = 31547654
577 + 31547077 = 31547654

Showing the first eight; more decompositions exist.
