Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562662, here are decompositions:

41 + 31562621 = 31562662
59 + 31562603 = 31562662
179 + 31562483 = 31562662
233 + 31562429 = 31562662
239 + 31562423 = 31562662
389 + 31562273 = 31562662
401 + 31562261 = 31562662
419 + 31562243 = 31562662

Showing the first eight; more decompositions exist.
