Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499706, here are decompositions:

47 + 31499659 = 31499706
107 + 31499599 = 31499706
113 + 31499593 = 31499706
239 + 31499467 = 31499706
307 + 31499399 = 31499706
379 + 31499327 = 31499706
383 + 31499323 = 31499706
397 + 31499309 = 31499706

Showing the first eight; more decompositions exist.
