Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499754, here are decompositions:

23 + 31499731 = 31499754
43 + 31499711 = 31499754
193 + 31499561 = 31499754
257 + 31499497 = 31499754
263 + 31499491 = 31499754
347 + 31499407 = 31499754
353 + 31499401 = 31499754
367 + 31499387 = 31499754

Showing the first eight; more decompositions exist.
