Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548982, here are decompositions:

29 + 31548953 = 31548982
233 + 31548749 = 31548982
239 + 31548743 = 31548982
389 + 31548593 = 31548982
419 + 31548563 = 31548982
431 + 31548551 = 31548982
449 + 31548533 = 31548982
461 + 31548521 = 31548982

Showing the first eight; more decompositions exist.
