Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474542, here are decompositions:

23 + 31474519 = 31474542
41 + 31474501 = 31474542
53 + 31474489 = 31474542
61 + 31474481 = 31474542
109 + 31474433 = 31474542
139 + 31474403 = 31474542
179 + 31474363 = 31474542
191 + 31474351 = 31474542

Showing the first eight; more decompositions exist.
