Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981632, here are decompositions:

31 + 981601 = 981632
109 + 981523 = 981632
139 + 981493 = 981632
151 + 981481 = 981632
181 + 981451 = 981632
193 + 981439 = 981632
241 + 981391 = 981632
313 + 981319 = 981632

Showing the first eight; more decompositions exist.
