Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558496, here are decompositions:

7 + 31558489 = 31558496
43 + 31558453 = 31558496
97 + 31558399 = 31558496
349 + 31558147 = 31558496
367 + 31558129 = 31558496
433 + 31558063 = 31558496
439 + 31558057 = 31558496
457 + 31558039 = 31558496

Showing the first eight; more decompositions exist.
