Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520606, here are decompositions:

37 + 31520569 = 31520606
79 + 31520527 = 31520606
97 + 31520509 = 31520606
109 + 31520497 = 31520606
127 + 31520479 = 31520606
199 + 31520407 = 31520606
307 + 31520299 = 31520606
373 + 31520233 = 31520606

Showing the first eight; more decompositions exist.
