Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486846, here are decompositions:

107 + 31486739 = 31486846
113 + 31486733 = 31486846
137 + 31486709 = 31486846
233 + 31486613 = 31486846
317 + 31486529 = 31486846
353 + 31486493 = 31486846
383 + 31486463 = 31486846
389 + 31486457 = 31486846

Showing the first eight; more decompositions exist.
