Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562382, here are decompositions:

53 + 31562329 = 31562382
83 + 31562299 = 31562382
101 + 31562281 = 31562382
109 + 31562273 = 31562382
139 + 31562243 = 31562382
151 + 31562231 = 31562382
263 + 31562119 = 31562382
283 + 31562099 = 31562382

Showing the first eight; more decompositions exist.
