Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498606, here are decompositions:

47 + 31498559 = 31498606
59 + 31498547 = 31498606
89 + 31498517 = 31498606
107 + 31498499 = 31498606
137 + 31498469 = 31498606
179 + 31498427 = 31498606
239 + 31498367 = 31498606
257 + 31498349 = 31498606

Showing the first eight; more decompositions exist.
