Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504544, here are decompositions:

157 + 31504387 = 31504544
193 + 31504351 = 31504544
241 + 31504303 = 31504544
457 + 31504087 = 31504544
571 + 31503973 = 31504544
613 + 31503931 = 31504544
661 + 31503883 = 31504544
691 + 31503853 = 31504544

Showing the first eight; more decompositions exist.
