Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520694, here are decompositions:

67 + 31520627 = 31520694
113 + 31520581 = 31520694
157 + 31520537 = 31520694
167 + 31520527 = 31520694
197 + 31520497 = 31520694
211 + 31520483 = 31520694
241 + 31520453 = 31520694
277 + 31520417 = 31520694

Showing the first eight; more decompositions exist.
