Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562706, here are decompositions:

23 + 31562683 = 31562706
29 + 31562677 = 31562706
79 + 31562627 = 31562706
83 + 31562623 = 31562706
89 + 31562617 = 31562706
103 + 31562603 = 31562706
113 + 31562593 = 31562706
139 + 31562567 = 31562706

Showing the first eight; more decompositions exist.
