Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498162, here are decompositions:

11 + 31498151 = 31498162
233 + 31497929 = 31498162
359 + 31497803 = 31498162
389 + 31497773 = 31498162
461 + 31497701 = 31498162
491 + 31497671 = 31498162
593 + 31497569 = 31498162
701 + 31497461 = 31498162

Showing the first eight; more decompositions exist.
