Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566602, here are decompositions:

3 + 31566599 = 31566602
13 + 31566589 = 31566602
43 + 31566559 = 31566602
61 + 31566541 = 31566602
79 + 31566523 = 31566602
313 + 31566289 = 31566602
433 + 31566169 = 31566602
523 + 31566079 = 31566602

Showing the first eight; more decompositions exist.
