Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562996, here are decompositions:

13 + 31562983 = 31562996
37 + 31562959 = 31562996
79 + 31562917 = 31562996
229 + 31562767 = 31562996
313 + 31562683 = 31562996
373 + 31562623 = 31562996
379 + 31562617 = 31562996
547 + 31562449 = 31562996

Showing the first eight; more decompositions exist.
