Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981862, here are decompositions:

53 + 981809 = 981862
131 + 981731 = 981862
149 + 981713 = 981862
179 + 981683 = 981862
239 + 981623 = 981862
263 + 981599 = 981862
293 + 981569 = 981862
389 + 981473 = 981862

Showing the first eight; more decompositions exist.
