Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514550, here are decompositions:

13 + 31514537 = 31514550
17 + 31514533 = 31514550
37 + 31514513 = 31514550
71 + 31514479 = 31514550
73 + 31514477 = 31514550
101 + 31514449 = 31514550
127 + 31514423 = 31514550
131 + 31514419 = 31514550

Showing the first eight; more decompositions exist.
