Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498586, here are decompositions:

37 + 31498549 = 31498586
73 + 31498513 = 31498586
307 + 31498279 = 31498586
313 + 31498273 = 31498586
373 + 31498213 = 31498586
397 + 31498189 = 31498586
463 + 31498123 = 31498586
499 + 31498087 = 31498586

Showing the first eight; more decompositions exist.
