Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504976, here are decompositions:

67 + 31504909 = 31504976
73 + 31504903 = 31504976
103 + 31504873 = 31504976
157 + 31504819 = 31504976
193 + 31504783 = 31504976
229 + 31504747 = 31504976
409 + 31504567 = 31504976
523 + 31504453 = 31504976

Showing the first eight; more decompositions exist.
