Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451594, here are decompositions:

7 + 31451587 = 31451594
67 + 31451527 = 31451594
73 + 31451521 = 31451594
103 + 31451491 = 31451594
157 + 31451437 = 31451594
211 + 31451383 = 31451594
271 + 31451323 = 31451594
547 + 31451047 = 31451594

Showing the first eight; more decompositions exist.
