Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460678, here are decompositions:

31 + 31460647 = 31460678
97 + 31460581 = 31460678
127 + 31460551 = 31460678
181 + 31460497 = 31460678
331 + 31460347 = 31460678
349 + 31460329 = 31460678
397 + 31460281 = 31460678
541 + 31460137 = 31460678

Showing the first eight; more decompositions exist.
