Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480494, here are decompositions:

53 + 31480441 = 31480494
61 + 31480433 = 31480494
103 + 31480391 = 31480494
113 + 31480381 = 31480494
127 + 31480367 = 31480494
293 + 31480201 = 31480494
433 + 31480061 = 31480494
547 + 31479947 = 31480494

Showing the first eight; more decompositions exist.
