Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458746, here are decompositions:

37 + 31458709 = 31458746
43 + 31458703 = 31458746
79 + 31458667 = 31458746
103 + 31458643 = 31458746
139 + 31458607 = 31458746
157 + 31458589 = 31458746
367 + 31458379 = 31458746
373 + 31458373 = 31458746

Showing the first eight; more decompositions exist.
