Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461394, here are decompositions:

53 + 31461341 = 31461394
101 + 31461293 = 31461394
113 + 31461281 = 31461394
233 + 31461161 = 31461394
281 + 31461113 = 31461394
347 + 31461047 = 31461394
383 + 31461011 = 31461394
443 + 31460951 = 31461394

Showing the first eight; more decompositions exist.
