Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562676, here are decompositions:

53 + 31562623 = 31562676
59 + 31562617 = 31562676
73 + 31562603 = 31562676
83 + 31562593 = 31562676
109 + 31562567 = 31562676
157 + 31562519 = 31562676
193 + 31562483 = 31562676
227 + 31562449 = 31562676

Showing the first eight; more decompositions exist.
