Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494004, here are decompositions:

5 + 31493999 = 31494004
53 + 31493951 = 31494004
293 + 31493711 = 31494004
431 + 31493573 = 31494004
491 + 31493513 = 31494004
557 + 31493447 = 31494004
683 + 31493321 = 31494004
947 + 31493057 = 31494004

Showing the first eight; more decompositions exist.
