Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446498, here are decompositions:

7 + 31446491 = 31446498
37 + 31446461 = 31446498
59 + 31446439 = 31446498
71 + 31446427 = 31446498
131 + 31446367 = 31446498
137 + 31446361 = 31446498
157 + 31446341 = 31446498
241 + 31446257 = 31446498

Showing the first eight; more decompositions exist.
