Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520734, here are decompositions:

107 + 31520627 = 31520734
197 + 31520537 = 31520734
251 + 31520483 = 31520734
281 + 31520453 = 31520734
317 + 31520417 = 31520734
347 + 31520387 = 31520734
491 + 31520243 = 31520734
563 + 31520171 = 31520734

Showing the first eight; more decompositions exist.
