Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981752, here are decompositions:

61 + 981691 = 981752
151 + 981601 = 981752
229 + 981523 = 981752
271 + 981481 = 981752
313 + 981439 = 981752
379 + 981373 = 981752
433 + 981319 = 981752
463 + 981289 = 981752

Showing the first eight; more decompositions exist.
