Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547926, here are decompositions:

5 + 31547921 = 31547926
89 + 31547837 = 31547926
233 + 31547693 = 31547926
317 + 31547609 = 31547926
419 + 31547507 = 31547926
467 + 31547459 = 31547926
569 + 31547357 = 31547926
587 + 31547339 = 31547926

Showing the first eight; more decompositions exist.
