Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981418, here are decompositions:

41 + 981377 = 981418
107 + 981311 = 981418
131 + 981287 = 981418
197 + 981221 = 981418
281 + 981137 = 981418
401 + 981017 = 981418
419 + 980999 = 981418
461 + 980957 = 981418

Showing the first eight; more decompositions exist.
