Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562652, here are decompositions:

29 + 31562623 = 31562652
31 + 31562621 = 31562652
41 + 31562611 = 31562652
59 + 31562593 = 31562652
101 + 31562551 = 31562652
109 + 31562543 = 31562652
151 + 31562501 = 31562652
211 + 31562441 = 31562652

Showing the first eight; more decompositions exist.
