Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547038, here are decompositions:

41 + 31546997 = 31547038
101 + 31546937 = 31547038
191 + 31546847 = 31547038
239 + 31546799 = 31547038
317 + 31546721 = 31547038
401 + 31546637 = 31547038
569 + 31546469 = 31547038
587 + 31546451 = 31547038

Showing the first eight; more decompositions exist.
