Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931642, here are decompositions:

3 + 931639 = 931642
71 + 931571 = 931642
113 + 931529 = 931642
353 + 931289 = 931642
401 + 931241 = 931642
443 + 931199 = 931642
449 + 931193 = 931642
461 + 931181 = 931642

Showing the first eight; more decompositions exist.
