Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562604, here are decompositions:

11 + 31562593 = 31562604
37 + 31562567 = 31562604
53 + 31562551 = 31562604
61 + 31562543 = 31562604
103 + 31562501 = 31562604
137 + 31562467 = 31562604
163 + 31562441 = 31562604
173 + 31562431 = 31562604

Showing the first eight; more decompositions exist.
