Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514586, here are decompositions:

7 + 31514579 = 31514586
13 + 31514573 = 31514586
53 + 31514533 = 31514586
73 + 31514513 = 31514586
107 + 31514479 = 31514586
109 + 31514477 = 31514586
113 + 31514473 = 31514586
137 + 31514449 = 31514586

Showing the first eight; more decompositions exist.
