Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498846, here are decompositions:

17 + 31498829 = 31498846
83 + 31498763 = 31498846
317 + 31498529 = 31498846
347 + 31498499 = 31498846
383 + 31498463 = 31498846
419 + 31498427 = 31498846
479 + 31498367 = 31498846
503 + 31498343 = 31498846

Showing the first eight; more decompositions exist.
