Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482742, here are decompositions:

59 + 31482683 = 31482742
101 + 31482641 = 31482742
173 + 31482569 = 31482742
191 + 31482551 = 31482742
233 + 31482509 = 31482742
353 + 31482389 = 31482742
449 + 31482293 = 31482742
461 + 31482281 = 31482742

Showing the first eight; more decompositions exist.
