Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562134, here are decompositions:

17 + 31562117 = 31562134
41 + 31562093 = 31562134
101 + 31562033 = 31562134
167 + 31561967 = 31562134
311 + 31561823 = 31562134
353 + 31561781 = 31562134
491 + 31561643 = 31562134
503 + 31561631 = 31562134

Showing the first eight; more decompositions exist.
