Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446100, here are decompositions:

3 + 31446097 = 31446100
47 + 31446053 = 31446100
89 + 31446011 = 31446100
239 + 31445861 = 31446100
251 + 31445849 = 31446100
311 + 31445789 = 31446100
419 + 31445681 = 31446100
449 + 31445651 = 31446100

Showing the first eight; more decompositions exist.
