Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496002, here are decompositions:

23 + 31495979 = 31496002
53 + 31495949 = 31496002
269 + 31495733 = 31496002
311 + 31495691 = 31496002
401 + 31495601 = 31496002
479 + 31495523 = 31496002
491 + 31495511 = 31496002
509 + 31495493 = 31496002

Showing the first eight; more decompositions exist.
