Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562956, here are decompositions:

107 + 31562849 = 31562956
179 + 31562777 = 31562956
353 + 31562603 = 31562956
389 + 31562567 = 31562956
599 + 31562357 = 31562956
683 + 31562273 = 31562956
743 + 31562213 = 31562956
839 + 31562117 = 31562956

Showing the first eight; more decompositions exist.
