Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446004, here are decompositions:

47 + 31445957 = 31446004
113 + 31445891 = 31446004
281 + 31445723 = 31446004
311 + 31445693 = 31446004
353 + 31445651 = 31446004
383 + 31445621 = 31446004
431 + 31445573 = 31446004
461 + 31445543 = 31446004

Showing the first eight; more decompositions exist.
