Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504348, here are decompositions:

251 + 31504097 = 31504348
311 + 31504037 = 31504348
419 + 31503929 = 31504348
431 + 31503917 = 31504348
461 + 31503887 = 31504348
569 + 31503779 = 31504348
599 + 31503749 = 31504348
839 + 31503509 = 31504348

Showing the first eight; more decompositions exist.
