Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449590, here are decompositions:

13 + 31449577 = 31449590
19 + 31449571 = 31449590
37 + 31449553 = 31449590
97 + 31449493 = 31449590
127 + 31449463 = 31449590
181 + 31449409 = 31449590
229 + 31449361 = 31449590
331 + 31449259 = 31449590

Showing the first eight; more decompositions exist.
