Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468994, here are decompositions:

31 + 31468963 = 31468994
397 + 31468597 = 31468994
421 + 31468573 = 31468994
523 + 31468471 = 31468994
541 + 31468453 = 31468994
547 + 31468447 = 31468994
751 + 31468243 = 31468994
967 + 31468027 = 31468994

Showing the first eight; more decompositions exist.
