Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504434, here are decompositions:

47 + 31504387 = 31504434
61 + 31504373 = 31504434
67 + 31504367 = 31504434
83 + 31504351 = 31504434
107 + 31504327 = 31504434
131 + 31504303 = 31504434
233 + 31504201 = 31504434
251 + 31504183 = 31504434

Showing the first eight; more decompositions exist.
