Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598520, here are decompositions:

7 + 31598513 = 31598520
61 + 31598459 = 31598520
71 + 31598449 = 31598520
97 + 31598423 = 31598520
101 + 31598419 = 31598520
103 + 31598417 = 31598520
139 + 31598381 = 31598520
157 + 31598363 = 31598520

Showing the first eight; more decompositions exist.
