Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550442, here are decompositions:

3 + 550439 = 550442
73 + 550369 = 550442
163 + 550279 = 550442
229 + 550213 = 550442
313 + 550129 = 550442
331 + 550111 = 550442
379 + 550063 = 550442
433 + 550009 = 550442

Showing the first eight; more decompositions exist.
