Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498506, here are decompositions:

7 + 31498499 = 31498506
37 + 31498469 = 31498506
43 + 31498463 = 31498506
79 + 31498427 = 31498506
139 + 31498367 = 31498506
157 + 31498349 = 31498506
163 + 31498343 = 31498506
199 + 31498307 = 31498506

Showing the first eight; more decompositions exist.
