Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520598, here are decompositions:

17 + 31520581 = 31520598
19 + 31520579 = 31520598
29 + 31520569 = 31520598
61 + 31520537 = 31520598
71 + 31520527 = 31520598
79 + 31520519 = 31520598
89 + 31520509 = 31520598
101 + 31520497 = 31520598

Showing the first eight; more decompositions exist.
