Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981772, here are decompositions:

3 + 981769 = 981772
41 + 981731 = 981772
59 + 981713 = 981772
89 + 981683 = 981772
149 + 981623 = 981772
173 + 981599 = 981772
353 + 981419 = 981772
461 + 981311 = 981772

Showing the first eight; more decompositions exist.
