Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464802, here are decompositions:

71 + 31464731 = 31464802
101 + 31464701 = 31464802
293 + 31464509 = 31464802
359 + 31464443 = 31464802
401 + 31464401 = 31464802
443 + 31464359 = 31464802
461 + 31464341 = 31464802
521 + 31464281 = 31464802

Showing the first eight; more decompositions exist.
