Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504606, here are decompositions:

59 + 31504547 = 31504606
113 + 31504493 = 31504606
167 + 31504439 = 31504606
233 + 31504373 = 31504606
239 + 31504367 = 31504606
479 + 31504127 = 31504606
503 + 31504103 = 31504606
509 + 31504097 = 31504606

Showing the first eight; more decompositions exist.
