Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498804, here are decompositions:

41 + 31498763 = 31498804
101 + 31498703 = 31498804
257 + 31498547 = 31498804
263 + 31498541 = 31498804
383 + 31498421 = 31498804
461 + 31498343 = 31498804
587 + 31498217 = 31498804
653 + 31498151 = 31498804

Showing the first eight; more decompositions exist.
