Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562302, here are decompositions:

3 + 31562299 = 31562302
11 + 31562291 = 31562302
29 + 31562273 = 31562302
41 + 31562261 = 31562302
59 + 31562243 = 31562302
71 + 31562231 = 31562302
89 + 31562213 = 31562302
269 + 31562033 = 31562302

Showing the first eight; more decompositions exist.
