Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535054, here are decompositions:

43 + 31535011 = 31535054
73 + 31534981 = 31535054
181 + 31534873 = 31535054
223 + 31534831 = 31535054
457 + 31534597 = 31535054
571 + 31534483 = 31535054
613 + 31534441 = 31535054
631 + 31534423 = 31535054

Showing the first eight; more decompositions exist.
