Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546804, here are decompositions:

5 + 31546799 = 31546804
83 + 31546721 = 31546804
167 + 31546637 = 31546804
251 + 31546553 = 31546804
347 + 31546457 = 31546804
353 + 31546451 = 31546804
383 + 31546421 = 31546804
467 + 31546337 = 31546804

Showing the first eight; more decompositions exist.
