Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447594, here are decompositions:

11 + 31447583 = 31447594
107 + 31447487 = 31447594
137 + 31447457 = 31447594
293 + 31447301 = 31447594
383 + 31447211 = 31447594
461 + 31447133 = 31447594
491 + 31447103 = 31447594
593 + 31447001 = 31447594

Showing the first eight; more decompositions exist.
