Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514534, here are decompositions:

61 + 31514473 = 31514534
313 + 31514221 = 31514534
421 + 31514113 = 31514534
433 + 31514101 = 31514534
547 + 31513987 = 31514534
577 + 31513957 = 31514534
607 + 31513927 = 31514534
643 + 31513891 = 31514534

Showing the first eight; more decompositions exist.
