Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465802, here are decompositions:

13 + 31465789 = 31465802
61 + 31465741 = 31465802
139 + 31465663 = 31465802
223 + 31465579 = 31465802
241 + 31465561 = 31465802
439 + 31465363 = 31465802
619 + 31465183 = 31465802
673 + 31465129 = 31465802

Showing the first eight; more decompositions exist.
