Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458374, here are decompositions:

43 + 31458331 = 31458374
97 + 31458277 = 31458374
313 + 31458061 = 31458374
463 + 31457911 = 31458374
631 + 31457743 = 31458374
733 + 31457641 = 31458374
991 + 31457383 = 31458374
1033 + 31457341 = 31458374

Showing the first eight; more decompositions exist.
