Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981612, here are decompositions:

11 + 981601 = 981612
13 + 981599 = 981612
43 + 981569 = 981612
89 + 981523 = 981612
131 + 981481 = 981612
139 + 981473 = 981612
173 + 981439 = 981612
193 + 981419 = 981612

Showing the first eight; more decompositions exist.
