Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551034, here are decompositions:

23 + 31551011 = 31551034
41 + 31550993 = 31551034
113 + 31550921 = 31551034
167 + 31550867 = 31551034
197 + 31550837 = 31551034
227 + 31550807 = 31551034
233 + 31550801 = 31551034
311 + 31550723 = 31551034

Showing the first eight; more decompositions exist.
