Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444802, here are decompositions:

13 + 31444789 = 31444802
31 + 31444771 = 31444802
43 + 31444759 = 31444802
79 + 31444723 = 31444802
211 + 31444591 = 31444802
229 + 31444573 = 31444802
313 + 31444489 = 31444802
331 + 31444471 = 31444802

Showing the first eight; more decompositions exist.
