Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562374, here are decompositions:

17 + 31562357 = 31562374
83 + 31562291 = 31562374
101 + 31562273 = 31562374
113 + 31562261 = 31562374
131 + 31562243 = 31562374
257 + 31562117 = 31562374
281 + 31562093 = 31562374
317 + 31562057 = 31562374

Showing the first eight; more decompositions exist.
