Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498358, here are decompositions:

79 + 31498279 = 31498358
271 + 31498087 = 31498358
349 + 31498009 = 31498358
379 + 31497979 = 31498358
487 + 31497871 = 31498358
499 + 31497859 = 31498358
601 + 31497757 = 31498358
607 + 31497751 = 31498358

Showing the first eight; more decompositions exist.
