Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497292, here are decompositions:

5 + 31497287 = 31497292
41 + 31497251 = 31497292
419 + 31496873 = 31497292
509 + 31496783 = 31497292
599 + 31496693 = 31497292
719 + 31496573 = 31497292
773 + 31496519 = 31497292
863 + 31496429 = 31497292

Showing the first eight; more decompositions exist.
