Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444682, here are decompositions:

109 + 31444573 = 31444682
193 + 31444489 = 31444682
211 + 31444471 = 31444682
229 + 31444453 = 31444682
331 + 31444351 = 31444682
433 + 31444249 = 31444682
523 + 31444159 = 31444682
673 + 31444009 = 31444682

Showing the first eight; more decompositions exist.
