Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562482, here are decompositions:

41 + 31562441 = 31562482
53 + 31562429 = 31562482
59 + 31562423 = 31562482
191 + 31562291 = 31562482
239 + 31562243 = 31562482
251 + 31562231 = 31562482
269 + 31562213 = 31562482
383 + 31562099 = 31562482

Showing the first eight; more decompositions exist.
