Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504190, here are decompositions:

7 + 31504183 = 31504190
61 + 31504129 = 31504190
103 + 31504087 = 31504190
139 + 31504051 = 31504190
229 + 31503961 = 31504190
307 + 31503883 = 31504190
337 + 31503853 = 31504190
349 + 31503841 = 31504190

Showing the first eight; more decompositions exist.
