Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562292, here are decompositions:

11 + 31562281 = 31562292
19 + 31562273 = 31562292
29 + 31562263 = 31562292
31 + 31562261 = 31562292
61 + 31562231 = 31562292
79 + 31562213 = 31562292
173 + 31562119 = 31562292
193 + 31562099 = 31562292

Showing the first eight; more decompositions exist.
