Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453036, here are decompositions:

59 + 31452977 = 31453036
233 + 31452803 = 31453036
317 + 31452719 = 31453036
353 + 31452683 = 31453036
359 + 31452677 = 31453036
449 + 31452587 = 31453036
509 + 31452527 = 31453036
617 + 31452419 = 31453036

Showing the first eight; more decompositions exist.
