Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504822, here are decompositions:

3 + 31504819 = 31504822
23 + 31504799 = 31504822
131 + 31504691 = 31504822
383 + 31504439 = 31504822
449 + 31504373 = 31504822
593 + 31504229 = 31504822
719 + 31504103 = 31504822
809 + 31504013 = 31504822

Showing the first eight; more decompositions exist.
