Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504046, here are decompositions:

73 + 31503973 = 31504046
163 + 31503883 = 31504046
193 + 31503853 = 31504046
199 + 31503847 = 31504046
313 + 31503733 = 31504046
373 + 31503673 = 31504046
487 + 31503559 = 31504046
577 + 31503469 = 31504046

Showing the first eight; more decompositions exist.
