Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562032, here are decompositions:

23 + 31562009 = 31562032
59 + 31561973 = 31562032
113 + 31561919 = 31562032
251 + 31561781 = 31562032
389 + 31561643 = 31562032
401 + 31561631 = 31562032
503 + 31561529 = 31562032
569 + 31561463 = 31562032

Showing the first eight; more decompositions exist.
