Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504856, here are decompositions:

37 + 31504819 = 31504856
73 + 31504783 = 31504856
109 + 31504747 = 31504856
283 + 31504573 = 31504856
499 + 31504357 = 31504856
673 + 31504183 = 31504856
727 + 31504129 = 31504856
769 + 31504087 = 31504856

Showing the first eight; more decompositions exist.
