Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520608, here are decompositions:

29 + 31520579 = 31520608
71 + 31520537 = 31520608
89 + 31520519 = 31520608
191 + 31520417 = 31520608
269 + 31520339 = 31520608
467 + 31520141 = 31520608
491 + 31520117 = 31520608
599 + 31520009 = 31520608

Showing the first eight; more decompositions exist.
