Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504646, here are decompositions:

73 + 31504573 = 31504646
79 + 31504567 = 31504646
193 + 31504453 = 31504646
457 + 31504189 = 31504646
463 + 31504183 = 31504646
673 + 31503973 = 31504646
919 + 31503727 = 31504646
1087 + 31503559 = 31504646

Showing the first eight; more decompositions exist.
