Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514740, here are decompositions:

53 + 31514687 = 31514740
113 + 31514627 = 31514740
167 + 31514573 = 31514740
227 + 31514513 = 31514740
263 + 31514477 = 31514740
311 + 31514429 = 31514740
317 + 31514423 = 31514740
431 + 31514309 = 31514740

Showing the first eight; more decompositions exist.
