Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478594, here are decompositions:

13 + 31478581 = 31478594
73 + 31478521 = 31478594
193 + 31478401 = 31478594
223 + 31478371 = 31478594
271 + 31478323 = 31478594
307 + 31478287 = 31478594
421 + 31478173 = 31478594
571 + 31478023 = 31478594

Showing the first eight; more decompositions exist.
