Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542606, here are decompositions:

19 + 31542587 = 31542606
47 + 31542559 = 31542606
59 + 31542547 = 31542606
83 + 31542523 = 31542606
97 + 31542509 = 31542606
127 + 31542479 = 31542606
149 + 31542457 = 31542606
167 + 31542439 = 31542606

Showing the first eight; more decompositions exist.
