Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498508, here are decompositions:

37 + 31498471 = 31498508
229 + 31498279 = 31498508
397 + 31498111 = 31498508
421 + 31498087 = 31498508
439 + 31498069 = 31498508
499 + 31498009 = 31498508
577 + 31497931 = 31498508
751 + 31497757 = 31498508

Showing the first eight; more decompositions exist.
