Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490592, here are decompositions:

5 + 31490587 = 31490592
19 + 31490573 = 31490592
83 + 31490509 = 31490592
103 + 31490489 = 31490592
113 + 31490479 = 31490592
131 + 31490461 = 31490592
139 + 31490453 = 31490592
193 + 31490399 = 31490592

Showing the first eight; more decompositions exist.
