Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562694, here are decompositions:

11 + 31562683 = 31562694
17 + 31562677 = 31562694
67 + 31562627 = 31562694
71 + 31562623 = 31562694
73 + 31562621 = 31562694
83 + 31562611 = 31562694
101 + 31562593 = 31562694
127 + 31562567 = 31562694

Showing the first eight; more decompositions exist.
