Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504706, here are decompositions:

3 + 31504703 = 31504706
139 + 31504567 = 31504706
349 + 31504357 = 31504706
379 + 31504327 = 31504706
487 + 31504219 = 31504706
523 + 31504183 = 31504706
577 + 31504129 = 31504706
619 + 31504087 = 31504706

Showing the first eight; more decompositions exist.
