Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534970, here are decompositions:

97 + 31534873 = 31534970
139 + 31534831 = 31534970
151 + 31534819 = 31534970
241 + 31534729 = 31534970
373 + 31534597 = 31534970
409 + 31534561 = 31534970
487 + 31534483 = 31534970
541 + 31534429 = 31534970

Showing the first eight; more decompositions exist.
