Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468902, here are decompositions:

41 + 31468861 = 31468902
53 + 31468849 = 31468902
79 + 31468823 = 31468902
109 + 31468793 = 31468902
271 + 31468631 = 31468902
313 + 31468589 = 31468902
331 + 31468571 = 31468902
349 + 31468553 = 31468902

Showing the first eight; more decompositions exist.
