Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451326, here are decompositions:

3 + 31451323 = 31451326
29 + 31451297 = 31451326
107 + 31451219 = 31451326
167 + 31451159 = 31451326
293 + 31451033 = 31451326
359 + 31450967 = 31451326
479 + 31450847 = 31451326
503 + 31450823 = 31451326

Showing the first eight; more decompositions exist.
