Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504792, here are decompositions:

89 + 31504703 = 31504792
101 + 31504691 = 31504792
131 + 31504661 = 31504792
173 + 31504619 = 31504792
311 + 31504481 = 31504792
353 + 31504439 = 31504792
419 + 31504373 = 31504792
563 + 31504229 = 31504792

Showing the first eight; more decompositions exist.
