Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562476, here are decompositions:

47 + 31562429 = 31562476
53 + 31562423 = 31562476
233 + 31562243 = 31562476
263 + 31562213 = 31562476
359 + 31562117 = 31562476
383 + 31562093 = 31562476
419 + 31562057 = 31562476
443 + 31562033 = 31562476

Showing the first eight; more decompositions exist.
