Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493962, here are decompositions:

11 + 31493951 = 31493962
53 + 31493909 = 31493962
173 + 31493789 = 31493962
179 + 31493783 = 31493962
251 + 31493711 = 31493962
389 + 31493573 = 31493962
443 + 31493519 = 31493962
449 + 31493513 = 31493962

Showing the first eight; more decompositions exist.
