Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539606, here are decompositions:

13 + 31539593 = 31539606
19 + 31539587 = 31539606
23 + 31539583 = 31539606
37 + 31539569 = 31539606
83 + 31539523 = 31539606
107 + 31539499 = 31539606
139 + 31539467 = 31539606
167 + 31539439 = 31539606

Showing the first eight; more decompositions exist.
