Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446370, here are decompositions:

3 + 31446367 = 31446370
29 + 31446341 = 31446370
41 + 31446329 = 31446370
47 + 31446323 = 31446370
113 + 31446257 = 31446370
239 + 31446131 = 31446370
269 + 31446101 = 31446370
317 + 31446053 = 31446370

Showing the first eight; more decompositions exist.
