Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451794, here are decompositions:

41 + 31451753 = 31451794
71 + 31451723 = 31451794
83 + 31451711 = 31451794
137 + 31451657 = 31451794
197 + 31451597 = 31451794
233 + 31451561 = 31451794
593 + 31451201 = 31451794
683 + 31451111 = 31451794

Showing the first eight; more decompositions exist.
