Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478734, here are decompositions:

167 + 31478567 = 31478734
251 + 31478483 = 31478734
263 + 31478471 = 31478734
383 + 31478351 = 31478734
401 + 31478333 = 31478734
467 + 31478267 = 31478734
563 + 31478171 = 31478734
587 + 31478147 = 31478734

Showing the first eight; more decompositions exist.
