Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476170, here are decompositions:

13 + 31476157 = 31476170
73 + 31476097 = 31476170
97 + 31476073 = 31476170
139 + 31476031 = 31476170
157 + 31476013 = 31476170
241 + 31475929 = 31476170
373 + 31475797 = 31476170
421 + 31475749 = 31476170

Showing the first eight; more decompositions exist.
