Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461604, here are decompositions:

47 + 31461557 = 31461604
71 + 31461533 = 31461604
191 + 31461413 = 31461604
263 + 31461341 = 31461604
311 + 31461293 = 31461604
431 + 31461173 = 31461604
443 + 31461161 = 31461604
491 + 31461113 = 31461604

Showing the first eight; more decompositions exist.
