Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546526, here are decompositions:

43 + 31546483 = 31546526
139 + 31546387 = 31546526
157 + 31546369 = 31546526
223 + 31546303 = 31546526
367 + 31546159 = 31546526
373 + 31546153 = 31546526
397 + 31546129 = 31546526
457 + 31546069 = 31546526

Showing the first eight; more decompositions exist.
