Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497832, here are decompositions:

5 + 31497827 = 31497832
29 + 31497803 = 31497832
59 + 31497773 = 31497832
131 + 31497701 = 31497832
263 + 31497569 = 31497832
281 + 31497551 = 31497832
383 + 31497449 = 31497832
389 + 31497443 = 31497832

Showing the first eight; more decompositions exist.
