Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504846, here are decompositions:

47 + 31504799 = 31504846
179 + 31504667 = 31504846
227 + 31504619 = 31504846
239 + 31504607 = 31504846
353 + 31504493 = 31504846
479 + 31504367 = 31504846
617 + 31504229 = 31504846
719 + 31504127 = 31504846

Showing the first eight; more decompositions exist.
