Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504854, here are decompositions:

53 + 31504801 = 31504854
71 + 31504783 = 31504854
107 + 31504747 = 31504854
151 + 31504703 = 31504854
163 + 31504691 = 31504854
193 + 31504661 = 31504854
263 + 31504591 = 31504854
281 + 31504573 = 31504854

Showing the first eight; more decompositions exist.
