Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498544, here are decompositions:

3 + 31498541 = 31498544
31 + 31498513 = 31498544
73 + 31498471 = 31498544
271 + 31498273 = 31498544
331 + 31498213 = 31498544
421 + 31498123 = 31498544
433 + 31498111 = 31498544
457 + 31498087 = 31498544

Showing the first eight; more decompositions exist.
