Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490594, here are decompositions:

7 + 31490587 = 31490594
67 + 31490527 = 31490594
97 + 31490497 = 31490594
211 + 31490383 = 31490594
271 + 31490323 = 31490594
307 + 31490287 = 31490594
313 + 31490281 = 31490594
337 + 31490257 = 31490594

Showing the first eight; more decompositions exist.
