Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489898, here are decompositions:

19 + 31489879 = 31489898
79 + 31489819 = 31489898
151 + 31489747 = 31489898
379 + 31489519 = 31489898
409 + 31489489 = 31489898
487 + 31489411 = 31489898
499 + 31489399 = 31489898
619 + 31489279 = 31489898

Showing the first eight; more decompositions exist.
