Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468992, here are decompositions:

29 + 31468963 = 31468992
73 + 31468919 = 31468992
89 + 31468903 = 31468992
131 + 31468861 = 31468992
199 + 31468793 = 31468992
293 + 31468699 = 31468992
419 + 31468573 = 31468992
421 + 31468571 = 31468992

Showing the first eight; more decompositions exist.
