Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562344, here are decompositions:

53 + 31562291 = 31562344
71 + 31562273 = 31562344
83 + 31562261 = 31562344
101 + 31562243 = 31562344
113 + 31562231 = 31562344
131 + 31562213 = 31562344
227 + 31562117 = 31562344
251 + 31562093 = 31562344

Showing the first eight; more decompositions exist.
