Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454742, here are decompositions:

5 + 31454737 = 31454742
41 + 31454701 = 31454742
61 + 31454681 = 31454742
73 + 31454669 = 31454742
89 + 31454653 = 31454742
229 + 31454513 = 31454742
281 + 31454461 = 31454742
311 + 31454431 = 31454742

Showing the first eight; more decompositions exist.
